I know that I am chiming very late in this but I believe in fuel additives that contain pea. I have done my own experiments with it and I even clean the carbon from my rifles with it along with my shooting club. We use Berryman B12 and it dissolves carbon fantastically! I have a suppressed AR-15 that gets huge deposits in the suppressor and the barrel. And B12 cuts through it like butter. In fact I wrote an email to convey my gratitude and tell them about the second use and they sent me two large 12 can cases! I wasn't expecting that but I was just floored. If you are a patriot, try it in your rifle. B12 has a secondary use and it's terrific. Berryman is a top notch company and they get my loyalty for the rest of my days! Please consider buying their products!
We are very fortunate to have you on youtube. Thank You.
Very kind, thanks for watching!
The reason why I like this guy's channel is because he doesn't go on bias observations, guesstimate or opinion yeah science b****
What a difference between your video skills from then to now. Been watching for over year . Your ability to use math to discover the end results of multiple cars is awesome. Really shows the ability of engineers to expect an outcome. Great work.
This kind of objective analysis is a breath of fresh air, compared to other internet sources. It's too bad there is no easy way to elevate objective discussion like this to a higher plane for internet search engines.
I was having issues with hesitation and rough running on my Chevrolet Avalanche 2500. After two cans of Gumout with PEA the 200,000+ mile 8.1L Vortex under the hood was running as best I can tell like near new. A third can didn't make any noticable difference so I figure I got the best out of the Gumout that I was going to get. Of note, the driver side OX sensor was noting an error on the trucks computer on occasion. After the two cans of Gumout, no more errors. I'm using Torque and reading the ODBC II so I can see the OX sensor is working again, comparing the reporting by the driver side sensor to the passenger side sensor. The cans were put in one at a time running a full tank of gas and repeating. I now run one can of Gumout once a year. Thank you for your testing and complete explanation of PEA. It works!
I admire YOU and your intelligence to keep 'US' informed. You're very through, explain in utmost detail and are as handsome as a NEWS BROADCASTER! (Take that as a compliment because you're NOT rude, NOT errogant and you take POLITE to new levels for all of us).
I stay tuned on your channel because You're helping me learn to me to be environmentally friendly, efficient and budget my money on items WORTH buying!
Thank you my friend
Whenever a question comes in mind, I open your channel and you are always there with an answer. Thanks a lot
It would be an interesting experiment to add some heat, and see how much additional affect there is on the reaction. The high speed flow at the intake as well as the heat from the combustion must be beneficial contributors to the cleaning action.
Hey there! First of all just wanted to thank you for how helpful your videos have been. It's helped me from knowing almost nothing about cars to finally being able to fix my 7.4l 454 v8 in my 85' suburban. I was wondering if you have or if you would do a video on better throttle response on carburetors and the different kinds there are? I was also very curious in learning more about an engines governor. Thanks again!

That is who he reminds me of. Thanks. For years I couldn't figure it out. Of course Brian Cox is at a whole other level, but I have a lot of respect for Jason though too

He should stay with his books, and leave us petrolheads alone
@@Kj16V Brian Cox is patronising? I've never even began to think that.
Ran two lots of injector cleaner through my 2.5 Diesel engine. I’ve been running it 20k it’s a good lump but I don’t know the history before I fitted it. It’s definitely made a difference on mpg going from average of 31 to around 33.5. And it feels slightly better. Next step is new injectors but as an interim measure for twenty quid it’s been worth it.
Great info and well done. You inspire confidence and demonstrate great credibility
This guy is so knowledgeable and researches extremely well. No bias opinions. Just honesty. Backed up by peer reviewed studies. Trust what he says for your car's health.
Can You do a video on Diesel engines Additives?, thanks for this video !
Never had a problem with cold starts before on my 84 Supra...now that I've stopped using gumout, it runs rougher, gets worse mileage, and takes at least 30 seconds to start on a cold day. This stuff surprisingly actually works.

Excellent video! I think it would be great if you did a follow up video on various types of fuel stabilizers. Personally I use e85 ethanol in my car and occasionally put in the lucas oil ethanol stabilizer and am curious if it actually does anything. Keep up the good work!
Excellent, greetings from Honduras, Central America
Hi, I'm curious. Does the carbon block the cats after moving out of the piston chamber. Thanks for your videos.
I'd us Cataclean to clean out your catalytic converter if you think it's dirty or it's time to clean it. Cataclean works awesome! It cleans injectors, o2 sensors, combustion chambers, and catalytic converter, and muffler. The muffler id the least likely thing to get clean, but it does help keep it from clogging. I've used it for years and it works. It's usually a little over $20. About $22- $26. So if you need to pass emissions or need to get rid of a o2 sensor code try a bottle of Cataclean on a 1/8th of tank of gas, and drive it for 15-20 or 15-20 miles whatever comes first, and then fill it up with fresh new gas.
ln theory if there was a massive dump of carbon that could potentially cause some cat blockage or at least throw a code but if you do the procedure correctly that won't be a problem. That's precisely why most of these products recommend your car but already up to operating temperature when you put the product in your gas tank. The reason for this is so that your cats are fully hot at the point that the cleaner starts loosening up the carbon deposits which will then get vaporized during the combustion process, pass right by the hot cats, and expelled out the exhaust. Also, at the right concentration levels, a certain amount of the cleaning agents will also get vaporized and make it to the cats and help clean up any residue build up. Of course that will not help if a cat is already damage, melted, disintegrated, etc, in that case you need a new cat, but for cats that have excessive residue buildup, the vaporized cleaning agents can also help clear some of that out and allow for a more efficient catalytic process. When l do a decarbonizing treatment of the fuel system, after the process is completed l do remove the upstream & downstream O2 sensors and leave them soaking for about 24 hrs in either plain gasoline a thin cleaning agent such as Seafoam, Berryman's B-12 which does a fantastic job of removing built up carbon and other contaminants from the sensor tips which are located behind the metal shroud. You will see a surprising amount of soot at the bottom of the glass container that you soaked the sensors in after letting soak for 24 hours. After removing them from the cleaning solution l then thoroughly spray them down with MAF sensor cleaner, using the little straw that comes with the spray can you can insert the straw in to the holes that are on the shroud and blast out remaining contaminants that may still be stuck inside the shroud, then spray down the outside to and give it a good wipe down. This will do a lot to keep your catalyst system working properly and efficiently for as long as you own the car. Some people do this O2 sensor cleaning process at the same time that they do the regular maintenance cleaning of the PCV valve, EGR, Throttle body which is a great time to get it all done together.
Hi, great videos. Would you review options to clean the valves on a direct injection engine?
Also keen to know what findings you can gather on direct injection fuel systems. Great work!
Excellent information in this video!!! You gave good facts, presented a lot of information quickly and made it understandable. This could be a how to for others making videos!!!
once again down to the facts in an easy to understand a simplified manner eh Great video. I have been a Licensed tech for 26 years. I tell customers to google your site for reference to my diagnosis, or answers to questions they are skeptical of my answers eh Keep up the good work.
Your vids are very well done and factual!!
Would've liked to see a "control_experiment" at the end with a similar item soaked in gasoline.
You and I both! Video was awesome until final 30.
I totally liked this video and your research ! Thank you !
I trust this CZcams engineer, that's why when I was looking for results I saw his channel and immediately saw this first lol!
Thanks for the vid. Nice info here. I'm wondering what would happen if you take the same piece of tailpipe and soak it in some gasoline instead of Gumout.
I have always thought of fuel additives as "cocktails for cars"; i.e. may not do much but they make you feel better. In Canada, the 87 octane gas can contain up to 10% Ethanol and it is my understanding that while this gas is perfectly suitable for cars that don't require anything with a higher octane, the number of additives put into it by the refinery may be less than their higher octane (read: more expensive) fuels. When the product is on sale, or when taking an especially long drive where I know I will be filling the tank more than usual, I like to add a bottle of additive. Same when I do an oil change; I like to add a 500 ml concentrate meant for older vehicles as most of my driving is city driving, short distances.
Fellow scientist here love the clear objective of proper research. No hear say just pure science
These videos are very educational, and with that also very professional! =) Keep up the good work.
I just watched this the other day but I was too stoned to remember anything, so here I am watching it again stoned. 😅
Wow you’re so coool mr stoney
@@thegreat9481 slam dunk!
Feel better?
I actually used a bottle of Gumout Fuel Injection cleaner in my 2005 Subaru Outback XT with the turbo ej255 motor. The wagon has 147k miles on it and started to develop a slight shudder at idle. I am half-way through the tank of gas with Gumout in it and a much smoother idle very noticeable and for five bucks it was well worth every penny. It is great to see a video that actually had an explanation as to how and why these products work along with an example. You have gained another subscriber! Thanks!
Thomas Poland Thanks for watching, and sharing your experience!
Thomas Poland
I know this is 2 years later, but I have the shuddering idle on my '08 subaru legacy at 62k miles. Damn it sucks
My strange studder goes away when the tires are at the proper pressure. 30psi rear and 32psi front. It is a strange situation, but it's livable.
Thomas Poland
(*long story*)
mine are always inflated slightly about PSI (as so I don't have to worry about when it gets cold and affecting PSI, etc). The shuddering is usually bad when the engine is warmed up and having been driven a while and I come to a slow down/stop or am sitting at red light (rpm drops from idle to 200-300 RPM) . Happens most when heat or AC are when.
Seems like the car being required to make more power brings the issue forward more. One day during a hot day when I was at a drive through, engine shuddered and shut off when I had the AC running. No check engine light or anything happened before hand.
Brought the car to my mechanic, he cleaned throttle body, air filter (which was already clean) checked air box, etc. Seemed to help the situation a little. That was a year ago.
Worst it got was last week. Engine sputtered and rpm dropped to 100 and check engine light flashed for a split second. Drove It to my parking lot and didn't drive it for a week until I was able to bring it to my mechanic.
There was a slight leak of what seemed to be power steering or oil, behind the alternator. My mechanic cleaned it and couldn't find the leak. He takes the car for three days and doesn't feel the shudder. He recommends me a gas cleaner to use and then get back to him. I'm waiting to use cleaner since I have to wait till tank is at 1/4 tank.
This entire process is just crazy.
Update please - did the fuel cleaner solve the problem?
again a great video, and you have a new subscriber!
as for additives, it explains my experience from a couple of years ago, when I was given additives as a sample from my friend who used to sell them, at first my car started running better it felt smoother and the fuel consumption went down, so I started buying the additive and using it regularly (in the interval suggested by the producer) and within 6 months my engine started working WORSE than before the additives! so I stopped using them, and used highest rated fuel I could buy for a couple of months and luckily it somehow cleaned itself and went back to normal!
this video makes me think I would have benefitted better have I cleaned my car originally with the additive and then just stopped using it, I think that would have been the best option
Dude! Awesome vid! Thank you! Keep posting more!!
bro you sound like a professor very informative well done!
Nice video. thanks for explanation as always. I guess (as an engineer myself) I'd be interested in the question: does using PEA to reduce the deposits improve the vehicles performance in some way? OR does it protect the engine in some way? those are the important end-measures in my opinion. Do you have any insight on those questions? Thanks again.
as a non college edumacated lowlife i find it fascinating you cannot derive the purpose of cleaning deposits out of a motor
Could you do a test of FSi or GDi intake spray cleaners? Not necessarily a 'which product is best' test but more an 'are they worth using' and 'what to look for' test. Keep up the great work!
Jason, Great videos, really appreciated the one on the pneumatic valves in the F1 cars. Along that line, I just read that the Mercedes F1 hybrid engine is running at 43% thermal efficiency! I always thought that getting close to 25% was really good! Explain how it is measured and how to improve it so much. Thanks
The studies you mentioned both are comparing "base gasoline" to gasoline with additives. Is "base gasoline" equivalent to what we buy? It was my understanding that the various gasoline companies have their own additive packages - including detergents and carbon reducers. So, is Gumout really necessary for any engine using real world pump gas versus the "base gasoline" used in the studies? Just like the number of licks required to get to the Tootsie Roll center: the world may never know....
John Gedde Probably not too different. Then you could always add smaller amounts than directed of the cleaner product into the gas tank, just to be on the safe side.
I've heard that Top Tier is all we need and if you use the cheap stuff (actually Top Tier isn't always more expensive, especially now that Arco is Top Tier) then running a bottle of Chevron Techron through every oil change is a good way to go.
Like your video's
Can you do a video on marvel mystery Oil (automotive additive)
Company states product was used in fighter planes WW11
Curious I've been using it for years in all my cars , bikes just about anything with a engine .
Says to add to motor oil and fuel.
A lot of mechanics including myself swear by it.
Thank you very much and thanks for the video's
Joe.. Ex navy veteran ..
I second that. Some things I know for sure are that it made my fuel pump quieter and gave be about 1 1/2 mpg better on average (in gas tank vs. just gas, same gas station every time) It also seems to provide better acceleration when in the crankcase, but that is probably because it thins the oil a little. I'd love to know what it actually does!
Thanks for sharing... love watching our vids. The last little test with the exhaust in the solution was a little flawed as I'm sure you knew... just maybe should add a qualifier. Numerous variables changed... different volume, temperature and time than what would be seen in an engine and could change effectiveness. All in all fantastic vids. Keep sharing.
Bg44 k platinum excellent product for cleaning carbon deposits
Great video, thanks for sharing. I've never heard of isopropyl alcohol as an additive but I've heard people talk about using acetone. What is your take on this? Thank you.
I performed a test to see if various fuel additives are safe on fuel lines; the video is on my channel.
Gumout did alright.
use it before or after an oil change?
Before.
Don't want carbon in your new oil.
Thanks for the information, it would be great if you explain how does injectors really work ,appreciate it .
Your explanations are really very Qualitative, it's really Quality time to watch your videos and really worth watching. I have old car and I'll try high Quality fuel rated 92.
The real conclusion is:
1. If you have a newer engine (up to 80K miles or so), don't use ANYTHING.
2. When your engine reaches 80-100K, use an additive every time you change your oil. I like to do it 400-500Km before changing oil because then I "flush" some of the deposits that got into the oil. I consistently see improvement in the gas consumption (10%-15%) when I measure it AFTER I finished the full "supplemented" tank, for about 2000-3000 miles. From that point on, my gas consumption becomes higher until the next oil change+fuel additive.
3. If you'll use it too much, you'll end up building more deposits than you're breaking. Deposits on the piston head might cause detonation.
Shane is it safe to use it without oil change
@@alecsanderfuentes3913
Sure, I just like to start fresh after the treatment...But there won't be enough deposits to make you oil sludgy. Just don't do it immediately after an oil change. You don't want your new oil dirty right after you serviced your car.
@@shane250 So do you use a fuel and an engine oil additive? If so, do you use a fuel additive after you do an oil change + oil additive or do you use the fuel additive before the oil change?
@@ZareefHuq
I use an oil additive because I got an old car (160K 2010). You do the PEA fuel additive as close as you can before your next oil change (so the oil change will flush the carbon you cleaned into your oil). Make sure you finished the tank with the additive before you change your oil. The oil additive (only if you use conventional crap from the garage pump...not if you buy some good oil) when you change the oil (put 1/2 a quart instead of 1/2 quart oil).
@@ZareefHuq If you use synthetic oil, NEVER use any oil additive.
I remember that red gas we had in the 80's
Very useful, thanks for the informative videos!
Thank you so much I work at AdvanceAuto and now I know that P.E.A is a reommended additive for both newer engines and older ones to clean the injectors better
Do you have an opinion on seafoam?
+duhstorm562 It's for 2 stroke

I've had seafoam fix my fuel gauge in a 2002 Ford Explorer 140k. I also believe it helped my 2003 jeep liberty 248k run better.
+Andy Shay those are all 4 strokes
Andy Shay what issue did you have in your fuel gauge? needle totally down?
Good info, thanks! Is using Premium or Plus grade gasoline worth the extra price? What about premium gasoline stocks with additives already in them like Shell V-Power, Chevron Techron, etc?
Use whatever octane is recommended by your manufacturer, no need to go to higher grades if your engine won't have a performance benefit from it.
I agree with EE -- use regular grade unless it's required for your car. Even then it's questionable. I had an HP Saab Turbo for which 93 octane was recommended. I ran it on 87 for 300,000 miles. Ran great, no knocking and fine performance.
Engineering Explained great video, as usual. I would love it if you did a video on straight cut gears or "dog boxes." you could even throw in strait cut diff's in the same vid! not to bribe you or anything, but I could provided you some support if you did this... maybe Mr.Lincoln could convince you? 😂
My car manual says Regular 87 is OK , but I've noticed that when using Regular, the engine oil seems to acidify very quickly, and the smell of combustion residue in the oil becomes noticeable. This seems to happen very quickly. And once it happens the oil is ruined and needs to be changed. Whereas when using Premium 93 gasoline exclusively, the oil stays clean for a long period. The combustion residue of the cheaper gas will be significantly greater than premium gas. While Regular Gas may not directly damage your engine due to knocking , it will significantly decrease the life-span of your oil. So using Premium Gas is actually beneficial, regardless of what your vehicle manual suggests is acceptable.
I am with the channel owner. Use what the car maker prescribes for your car.
Most cars will run just fine with any grade fuel, because for modern engines there are electronics to adjust the fuel injection for a wide range of fuel grades and operating conditions. With a higher grade fuel the engine will not gain more power, but a lower grade fuel may cost you a few hp which most of the time will not even be noticeable. There is a lot of fluffy marketing from car makers but they do not have any benefit by recommending a fuel grade that is not the best for an engine.
- The superpremium - platinum - viagra100 fuels that are sold like champagne are propaganda only. There is no car in the market where the electronics are adjusted to this.
- Avoid pumps that may have stale fuel, some Regular pumps are frequented very rarely!
impossible no to understand what he explains in every video thanks a lot for giving this guy his space on internet
Thanks for making this video!
I think this is good as far as it goes. The Fuel that you buy at the pump these days is not what used to be available in the past. Most fuel retailers and their up chain suppliers are forced to sell a blended fuel with ethanol, which not compatible with most components in the fuel system. Also fuel is not blended to be as stable as it once was. Fuel is meant to be burned within a 30 day period and peaks at about 10 days. Top tier fuel that meet higher standards will also reduce combustion by-products when used. Shell is my fuel of choice and does a good job in my personal ICE's when examined by bore scope. Always use the octane fuel intended for your specific vehicle and a high quality fuel will help to ensure a long and healthy life with fewer problems while in service.
Robert Phelps go with Shell. no ethanol
LuckRenewal most stations have 10% ethanol in the D.C. Area all do that I know of
+JAY WASSERMAN i agree. most stations here in toronto says "may contain up to 10% ethanol" at the pump. but shell declares that they have 0% (i think it's below a certain detectable limit that they can declare that) for their V-power gas.
1. California MANDATES ethanol (to reduce winter emissions) so we are stuck with it.
2. I thought modern anti-knock sensors and ECU's (engine control computers) were flexible in adapting to fuel quality - they will increase the performance on-the-fly if you use higher octane fuel. I definitely recall models that say the spec'd horsepower is based on Premium, but the car will run fine on Regular if you prefer. And vice versa, cars spec'd with Regular that pick up a few horsepower on Premium. But I'm not sure if all cars do this or only Euro models.
Its funny I was just getting some fuel like 2hours ago and wanted to know more about these products on the shelf, then I wondered if this guy had done a video on it and BAM. Law of attraction
Gday, just found your channel, thanks for the extremely well researched and presented video.
I love your content! I've watched tons of them having no idea I wasn't subscribed! Fixed that though!
is there any risk of these cleaners doing harm to parts of the engine like gaskets, or the fuel pump?
+Wynton Sparks I second this.
+Wynton Sparks - I tested some cleaners, including the Gumout motor treatment, on some fuel line. Some of the cleaners did seem to affect the rubber; you can see the results on my channel.
Rubber gaskets in cars might not be made for this type of additives and could damage them in some way (make them weaker) , if you love your car and want to keep it in top shape for a long time try not to use additives too much , once a year or twice at most
Not sure your 'Soak Test' is valid since the product is intended to be used during combustion. Interesting to hear about carbon equilibrium occurring around then thousand miles.
Thank you for the knowledge
Good video. I constructed an injector cleaner for on vehicle use out of pvc that goes directly to the fuel rail. I used the motorvac mv3 chemical because I got it for free at Napa. Made a huge difference in performance. Even made a video about it.
This stuff cleans out your carbon on engines that have been reasonably well taken care of. Its not gonna fix a blown head gasket, a spun bearing, a bent valve, a cam ran flat, or patch that window in the side of your block where you threw a rod. The people who buy this stuff are usually the people who are 5 years late on routine maintenance, and that is not who this product is for.
maybe the most important thing not mentioned is that a lot of these "cleaners" have stuff in them that can actually melt and/or deform the fuel filter gasket in your tank... which is never a good thing
if it deforms it might impede fuel flow, and worse case the fuel filter ruptures or melts allow a lot of gunk & debris to enter you fuel injection system... and the cost of replacing a fuel injection system is much higher as the cost of "added consumption" because of dirty valves.
+RnRollie - I performed a test to see if some of these motor treatments would affect the integrity of fuel lines, and some of them did seem to affect the rubber. I've got the video on my channel.
Good question. Marvel says it can if you go over the recommended on their web site.
Excellent info.Keep up the good work.Thank you.
Very informative, thanks!
in your test, you soak the part in the additive or the additive mixed w gasoline? Also what's the effect of burning rather than soaking?
Yes, i was thinking the exact same thing. Wouldn't getting the product heated (combustion proces or forced (injected) onto the valves) have a significant improvement in the overal effects of the product in comparison to just let is soak on the particals?
+J Segal In the beginning he said PEA was stable and did not change when burned.
Mark G So after combustion, the additive is left behind? Nope, that can't be correct. The point of an additive that "cleans" carbon buildup is usually that it in some way reintroduces the carbon into the combustion, by raising the temperature of the burn or maybe loosening the bond of the carbon on the surface or both. Anything not burned away makes things worse. The soaking would relate only to standing fuel, as in the tank. Some additives prevent corrosion or reduce water separation in tanks.
+J Segal The PEA doesn't burn. If it had to burn to work, then it wouldn't clean the intake valves. It just breaks the carbon loose and then it and the loose carbon gets forced out the exhaust.
It gets forced out as a gas or vapor, not as just chunks. If it dribbled out it would just redeposit in the exhaust. Knocking the carbon loose with a flammable agent allows it to be reincorporated into the burn and more fully exhausted. That's how carbon deposits are "cleaned" or removed. Technically, you reburn them, but more completely.
Isn't SAE claiming that fuel additives worsen deposits?
It stated that base gasoline left fewer deposits than using any additives, but that PEA was the lesser of the evils as it added less deposits than the other active ingredients used. Wouldn't this indicate the cleanest combustion chamber comes from no fuel additives?
This is also backed up by the data from the scientific paper you put up. The intake valves lost 72% of deposits, but the combustion chamber GAINED deposits (21%), similar to the SAE study.
On gumouts in house study they only mentioned intake deposits and ignored combustion chamber deposits.
As far as I can tell this means that fuel additives, specifically PEA, can clean intake valves but actually worsens deposits in the combustion chamber. Generally combustion chamber deposits are worry some due to the irregular combustion characteristics that can ensue (knocking, dieseling, etc) which makes this video incredibly misleading to those who don't pay close attention.
Unless I am completely misinterpreting this it seems to me my favorite youtube engineer sold out and is providing misinformation for profit :/, please prove me wrong.
I think his conclusion was more that valve deposits would be lessened, but overall deposits (e.g. heads) would be more. I'm inclined to agree with you though, not sure if it has something to do with Gumout sponsoring the video...
The conclusion of it was that using it periodically is good, but using it long term(like at every fillup) is bad. It appears to suggest every 10,000 miles, as that is how long it takes for carbon deposits to return to equilibrium.
Remember that the SAE test used NEW parts for every test. This is why he said for newer / cleaner engines, don't use it because it will add more deposits.
For older engines / dirty ones, the risk of adding more deposits is outweighed by the deposits that are already there.
You are spot on , except that the deposit build up will not cause dieseling or pinging but on the contrary will increase the compression ratio.
congrats on 1mm subs!
Great presentation.
more additive reviews!
good research... one thing that could have been changed, to be more precise with the carbon removal test, that you did with the muffler. Would have been to correctly mix the ratio of the additive to gasoline, and THEN letting it sit in a bowl......because testing the additive alone may not have the same affect, as testing with high quality gasoline mixed in.
Great video. Thanks.

Love your videos, keep up the good work!
Liquimoly (MoS2) is the best oil additive you can add to any engine.
Invented last century and proven in the WWII, is far the best real anti-friction additive, increasing millage per gallon, engine life, lowing friction and temperature, extending the oil life twice and other benefices.
I used it for over 20 years in a large number of gas/diesel vehicles and I never had a engine problem. Motorcycles beware cant be used in engines with yellow metals (bushing).
Very under rated in many countries specially in the US.
Mr E - Just added a 300ml bottle to 5 qts of Royal Purple 0-20 on my 2015 Scion tC. I've had a 2011 and a 2006 and have ran RP on both (alone, though) and the engine performance was noticeable. Also, the engine was quieter and "smoother" per se. I added a 300ml bottle to the RP and I must say it is absolutely great stuff. I can't say how well it would work with using another oil such as M1 or Pennzoil but I am now a fanboy of MoS2. Great stuff.
MoS2 is the best but keep it away from yellow metals.
Archoil AR9100 Friction Modifier!
so all that gunk travels where>?
catalytic clog central?
Great channel, mate!
Thank you. Excellent video as you usually do. Your findings correlate roughly with "Scotty's" recommendation for using the "Gumout" additive.
How about some one putting seafoam to test by using it on a high mileage engine and see how much horsepower is restored after using it.
Wait, the info was cool but the conclusion seemed wrong. Evidence showed an increase in carbon buildup on certain parts of the engine vs base gasoline. And the conclusion is PEA can help get rid of buildups? Well that's fine and dandy for the intake, but what about the heads and exhaust? What about differences in performance and fuel economy.
Your conclusion seems empty... Sorry if I am being pedantic.

Good point!
+David Love There are two kinds of deposits discussed in the video: intake valve deposit (IVD) and combustion chamber deposit (CCD). PEA gets rid of IVD, but may increase CCD. This is why EE recommends only use the additive if you have an old car which has IVD. There is a trade off in using fuel additives.
+icekk007 right on. I could jave missed that.
icekk007
Thank you for your explanation ;-)
Glad that I can clarify.
u are a very good tech..keep up the great work
I was looking for info on additives, and this was a over load, haha but better than underinformed i geuss. thanks for the video man.
what is techron from chevron?
It also uses PEA, though I don't know what all of the additives are.
+Engineering Explained What do you think about the lucas fuel injector cleaner? I hear that it is the best injector cleaner to use. Would you recommend using it on the V6 VTEC? I'm just wary of using any additive in my engine. Am I being too paranoid?
+Engineering Explained what is price of this aditives ??
+Ivan Bender Like $5-$10 bucks at your local auto parts store.
+Engineering Explained Basically techron is sea foam??
+Engineering Explained - What would be considered " High Quality Gasoline"?
+johnathan wood At a minimum something considered "top tier." Here's a list: www.toptiergas.com/retailers/
+Engineering Explained - I have to say, the that site seems like BS. According to that site just about every fuel station in my area is top tier... which with tests I have done... I know is not true. I have had about 160 used vehicles now.. So I have had the opportunity to use many different fuels in many different vehicles. With my testing, I have found that Chevron gives me more miles and more power when I drive. As fuel staions like Arco, have made my vehicle's mpg go down. With the same driving. Going from one station to another, I can deffinetly feel a difference. Especially with used vehicles that have lots of miles.
+Engineering Explained - Also, I wouldn't rate all those stations the same. I have filled up gas cans before and payed for exactly one gallon at different stations and been given different amounts of fuel. One pump didn't even pump out a drop of fuel until the total went to almost $1.
+johnathan wood Such a gas pump should be reported.
If that was state side, report it, fuel station owners can face felony charges for not maintaining the pumps, and pumps are supposed to be inspected yearly in most states, by a state authorized company for accuracy.
great job !!! Love your channel
Interesting stuff. Would this increase your mpg too by cleaning out the cylinders?
