Fuel Additives Don't Work - Here's Why (Shocking Results!)
Vložit
- čas přidán 16. 04. 2022
- Taryl and Ronnie decided to redo the fuel additives experiment and this time let the engines sit over the winter for about 5 months before attempting to start them. They were SHOCKED by the results they got when attempting to start them and then cracking the bowls on each engine. Taryl used some different additives this time around as well so be sure to check out which ones did their job and which ones failed. Between Taryl's 19 month fuel additive experiment and this test, there's some truly amazing results and speculations as to whether or not these additives actually work. So sit back and enjoy the ride... And as always, There's Your Dinner!!

Excellent experiment. Thank you for sacrificing Ronnie's home for several months to help solve this mystery.
It's OK! Ronnie was in jail for most of it :-))))
Add fuel shut off valve’s and run them dry before storage. That’s the best treatment in my opinion.
Better, but not best. Draining tank also would be best so there is no fuel to go bad. Then you can store it for years
Yes, and I have been adding a bit of oil to the tank after I pull the gas out of it, before running it dry. The oil coats the inside of the carb.
I leave the fuel with a stabilizer in the tank. I just shut the valve and run dry. The gas has always been fine after winter here in Minnesota.
If I stored it for years I’d run them dry.
a dry carb can build scale which can also clog a carburetor
Been doing that for years, everything except the generator that one I empty the whole fuel system

Thanks for the Summary Results. I'm going to have to rewatch again to see which of the "clean" additives also started quickly/ran smooth too.
Sad they didn't at least run extended/additional tests (or have they? Original Plan suggested a 10 month (total test) revisit) on the "new" additives that didn't Gel Up/Rust during the "Winter Storage" test. Given they "might" possibly perform better then the other samples that all were failed/failing after an extra 14 months.
Would be interested in seeing how the Walbro (Evergreen scented?) and Lucas products fair after extended storage (Maybe an "extreme" test with vented cans under poor weather/environment for 2-3 months? Might simulate a "forgetful" user that didn't properly seal a Gas Can or is using old fuel for treatment?)
Thanks for doing what Taryl SHOULD HAVE DONE. He should be pinning your comment at the top!
I enjoyed this journey. I did a similar test back in the ‘90s and into the 2000s. Ended up with close to the same results. Later on in 2015 I tried the test again with newer equipment and newer products. In my tests then, SeaFoam and Mechanic In A Bottle were the absolute worst. If I had a dollar for every time I’ve had someone argue with me over the best fuel stabilizers in the last 30 plus years, I wouldn’t have to turn wrenches anymore. Non ethanol fuel is the best fuel treatment.
I think non ethanol fuel and Sta Bil Storage will continue to be my go to fuel plan.
Well like they say, all good things must come to an end! Thanks Teryl for your dedication to this project. Now you can concentrate on more Service Bulletin Classics! 😁👍
I’ll just stick with non ethanol fuel with no additives, I’ve never had carburetor problems on any of my equipment. I’ve got equipment that’s 5 years old and it sits with a full tank after every use. Store them in winter all completely full of fuel that way you don’t get condensation in the tank
Yup same here .. I pay .50 more a gallon never had any probs ... unless it’s a Nikki carb I throw that in the garbage
Some of us aren’t lucky enough live where that’s available….
@@notajp Ethanol gas is a disaster in so many ways. First of all it actually puts more carbon in the atmosphere than the alternative. You need to tell your representatives to stop it
Yes sir. My experience is the same. I try not to store fuel over the winter, use it up or transfer it to a gas vehicle.
can't find ethanol free fuel here. maybe it'll get better when they add more ethanol to the fuel.
my gas will look like jelly within 3 months.
Taryl needs to start preparing for his trip to Oslo to accept his Nobel Prize for Science.
I like the bowl nut design because it's simple to clean with welding tip wire - I had that on my toro lawnmower (owned for over 25 years) and had to clean it 4 times
Or you can get another bowel jet nut and rotate them after cleaning !
Happy Easter Taryl!!!!👋🏼🇺🇸 🐣
It's great to see Ron in more videos. 👌
Very interesting video especially when you took the bowls off. Great reference when choosing a fuel stabilizer. Thanks Taryl for my dinner.
I haven’t purchased a new mower in a while, but the owner’s manual for all of my Toro equipment whether it be a mower or snowblower have all stated to drain the tank and run the engine out of fuel before storage.
I have followed this procedure and the only carburetor issues I have experienced have been dirt or wear related issues.
Thanks for the fuel tests Taryl, it was interesting to see the results of leaving fuel in equipment through the seasons.
Ive left weed eaters for 1 year and start fine. I think the 2 stroke oil mixed in helps preserve the gas. And in New Zealand we don't use ethanol in general
Mmo isn't meant to be a fuel stabilizer. It's for lubing and cleaning.
Exactly !!!!! Should not be included in the test !!
He should have noted that there were no big globs of gel, because the MMO was doing its job and breaking down the gel.
Can only add my 2 cents, I've been using Sta -bil for 30+ years the Marine and now the 360 in all my equipment and muscle cars for storage over the winter with never a problem and that's with 10% fuel. But I never push it over 5 months draining it out and refilling if need be and some equipment like the snowblowers and leaf vacs I store with tanks full and don't drain plus I use it year round.
I wonder if the "fuel stabilizer" claims of the older brands, such as Seafoam or MMO, were that they kept the classic non ethanol type gas fresh? Those formulas would have pre-dated the modern ethanol fuels most likely right? Remember there was a time when we stored nothing but non ethanol regular gas and I'd guess they're not made to do anything special with ethanol. Remember how it would turn into that varnishy smelling stuff after a while and fuel stabilizer was supposed to keep it fresh longer?
Would be interesting to see non ethanol gas with stabilizer in it and see how long it lasts.
MMO is not a stabilizer. It is a "extra" lubricant...
Teryl has videos with nonethanol pump fuel gas 🎵 that you could search. I'd bet (but could definitely be wrong) that companies that produced additives preethanol have updated their formula for ethanol.
Great test Taryl !!!!
I was GLUED to the screen !!!!
A summary chart like Project Farm uses would have been icing on the cake.
Rewind the video
👍 Happy resurrection day taryl & crew
This was a great experiment to see in real time.
Great job on this one guys... The whole series was really good....
I know you were having a little fun there, calling them all snake oil, but some did seem to work for the 5-6 months.....
I admire the dedication, to stick with this test, and really do it, for such a long term. Very well done.
My thoughts exactly, great test overall, but some do seem to help for the half a year test. None of my stuff sits more than that, and if it does, I drain the carbs, and keep the tanks full but cycle the fuel every now and then.
That being said, I wish E0 was available closer to home, it’s the way to go with a small engines.
Hey Taryl, the wood you built that engine stand out of, is worth more than the engines combined!
One thing I couldn't help but notice is that the rust was shown on those that are near the outside opening. Maybe this is why there was rust on the bowls there? Love what you do!
This one didn't get listed in the playlist. Very good test series, I loved it.
Received my order from your online store of the small licenses plate and the HV350 glue, Thank You and Thank you for the free sticker. First time placing an order long time fan.
Having watched the video about sandblasting the float bowls, I can't help but get a big smile when you come back to the topis. 😆
Thanks a lot of this series. Been very educational.
I use E0 high test gas in my OPE. No problems at all. I sometimes add a small dose of 2 cycle oil to the 2 gallons of gas but that's hit or miss, so no difference over winter.
Brillant work gentlemen. I use that term loosely, Ronnie. I agree with your findings. And all of them after about nine months are going varnishey quick. So that “up to 2 years” claim on most of them, is well, snake oily. The keywords that protect their claim are “up to”. You can smell the difference also, when its going sour. Correct in also stating the alkali fuels are best for storage and protecting the rubber and plastic. I dont think theres as much power from those those fuels, haven’t tested that myself, but have been advised that. I dont think in lower horsepower engines thats a big deal, but in higher ones you might not be getting “all of it”, like the feller going by in the begging of the video. Lol so another thing to consider is since ethanol and methanol are alcohols, modern gasoline is full of water right from the pump. They claim the O2 in alcohol is to help the catalytic converters, but i think it was before alcohols in fuel, water would sit in the storage tanks at ports and have be accounted for in the selling price, and have to be purged from the tanks every so often. Now all of that extra volume from humidity/condensation can be sold as gasoline and “up to” a third more in profit. Free money for the oil companies. You can take raw fuel from a pump, put it in a jar, and reverse the process. And then see how much of your gasoline was actually water. Im sure theres a proper youtube video for it. Again thanks for your great video and solid scientific advice. Mahalo! 🤙🏼😎🌴🌋👍🏼
This reminds me. I need to pick up some non-ethanol fuel today.
Taryl needs a mustie1 coffee mug to drain carbs bowls into
I have added a body hammer and a white coffee cup to my garage work bench
Great show, interesting results. Thanks for the look!
Great info guys Thanks for sharing 👍🏻
I love these videos, thanks
So, because the straight 87 octane jelled, we rule out that the jelling was caused by the additives breaking down.
Thanks! Gordonsville, Virginia
I'm so fortunate to have non-ethanol fuel available in my little town. Very informative series. Thanks!
Aspen is the best - nice products made here in Sweden. Use it for all my equipment - has a due date of 2 years so it starts all the time. Cheers!
It's a popular non ethanol Alkalyte fuel in the UK as well and is getting more popular everyday due to customers getting fed up with starting issues with equipment.
It would’ve interesting to test gas from different gas stations. Each gas station chain uses different additives that may or may not have an effect on ethanol buildup. Some busier gas stations like the ones along a highway or rest stop might have their storage fuel tanks filled more frequently so the gas is always fresh(?). I think it’s worth testing. Shell, Sunoco, BP, Chevron, Mobil, Sheetz, WaWa, Exxon, and Citgo just to name a few. I know there’s no way to test every single gas station brand but at least test the popular ones that are most common across the country or your area.
the bp's Indiana whiting plant refinery " can produce enough gasoline each day to support the average daily travel of more than 7 million cars" ; the question is , that same gasoline produced is it delivered to the different gzs stations in the area and beyond
Great job! Nothing like a real world test that gets to the bottom of this terrible problem. I’ve always used Marvel and had good results.
I love that ball shaped air tank in the lower right in the very beginning of the video.
Interesting test, start to finish.. personally I drain carbs on anything I can. The lawn tractors I fill with fresh gas and Stabil at beginning of storage then make sure to run then for a good 20 minutes every couple months during the winter and early spring. There’s your dinner!
The mechanics at our local marina tell me that ethanol causes no end of fuel system problems for them. Fortunately the marina sells non ethanol gas and I have no problem. The tests by TD have been really interesting and useful. I think it's a ripoff that some of these products caused more damage than doing nothing, such as the gelled gunk in the carb bowl. My sense is that if you can use non ethanol gas in your power equipment, then drain tank and carb for storage, you should be ok. Also, I mix one ounce of Gumout in the gas I use for power equipment to help keep the carb clean. Never had a carb problem.
It's interesting that the Tecumish started on the first pull.
Great fuel experiment happy Easter 👍
We call that gel “the grey goo” back in the day when ethanol was introduced to gas all the service stations were required/recommended to have they’re tanks pumped
out in order to receive the new gas.
Well one station (owned by cheap skates) decided not to. In my state up to 3” of water was allowed by law in the bottom of tanks, I delivered the first truckload of gas to this station and within a day the station was shutdown. All that ethanol had separated and the grey goo plugged up all the filters and became a gelatinous slime ball inside the in ground tank. Needless to say the removal process cost a lot of $$$$, but hey it was self inflicted the owners were cheap skates and very wealthy so hitting them in the pocket book was the only way they would learn.
Wow , thats crazy . Here in Calif . I worked for one of the majors and we never had any problems like that . Maybe something else like all that water stirred up when you unloaded cause it ? Who knows ?
Well after all that experimentation. I'm going to add fuel shut offs and run equipment dry whenever I can.
The Star Tron results match my experience. I usually always drain the tank on my snowblowers but my new Ariens holds a lot of fuel and we barely got snow the winter of 2020/2021. Big mistake as it started surging quite bad when I went to use it the following season. Normally I wrench on my own stuff but since it was a year old and still under warranty, I brought it in, and found out it had gummed up. Rec gas with Stabil for me now during the season, and back to always draining the tank in the off seasons.
Lol so many times here! Gas conservatorship really got me! Keep it coming guys.
Thank you!
Good test guys!
Taryl it would be interesting to load test the old fuel to see if it has the same output.
Maybe a generator under load or a pony brake to make a simple dyno
All good things must come to an end....Running them dry and/or the engineered fuels is your best bet
What fuel treatment do you recommend
Clean as a whistle
That saying is in reference to a steam whistle on an old time locomotive
All of my small engines which are all from the early 90’s have always been drained of fuel at the end of the season and none of them have ever has their carbs rebuilt, they start up like new every new season, so I agree with Taryl that them additives are just snake oil. Drain your fuel every season and we have access to non ethanol fuel where we live and that is what we use. Thanks for sharing the video.
What about your tank rusting?
That is the way to go.
I drain my Honda sno blower in the Spring. Put some Mystery oil in the cylinder.
Spray the empty gas tank with WD-40.
In the fall, I fill her up with premium non-eth and fire her up...
15 years and she runs like new !!
@@peteosinga8845 - all my tanks are plastic but we live in a very high humidity place during the summer and I have never had a moisture problem in my tanks
Best "stabilizer" you can use, is full synthetic outboard 2 stroke oil. (Johnson, quicksilver, ect.)Little smoky on startup, but have not cleaned a carb on any equipment I own for over 6yrs, and I use plain old 87 with ethanol.
Ethanol eats everything . It also attracts water . The pump says up to 10% alcohol may contain less at times . This makes a difference .
It doesnt attract water but it seems like it does, it stabilizes water longer than gasoline so while the gasoline seperates from the water and evaporates the ethanol is left behind with the water. Like the last one out turns off the lights and is left with the bill. i feel sorry for ethanol, if it wasnt there gasoline would gum up and be tacky flakey and dirty much quicker like it used to, then the carb would clog anyway. Either way a guy has to clean that carb often.
Great video my friend 👍 we use alcylate fuel for storage it works the best 😁
Great video. 5 months is a lifetime+1 for gas. I can't help but wonder how it even started with the gas at the point where it started gelling. I guess seeing is believing though.
As you found out in the previous experiment the 93 octane E10 super unleaded branded which is the standard unleaded in the UK is causing more starting issues over here in the UK. Apparently after 30 days from the pump the 93-95 E10 fuel starts to deteriorate. Most likely its shorter shelf life is because it has to travel from abroad before it gets distributed to the pumps. We see no issues yet with the 5% E5 super unleaded 95-99 octane fuels which are the recommended fuels for vehicles and machines with carburettors.
Hi Taryl I love your channel so I have a question for you all the way from England. Could you tell me what is the fastest cutting walk behind lawnmower that has ever been available to the public.
That would be without home modifications? I think this question is really hard even for a man of your high intellect. Keep making the videos please and I hope yourself and slippers can visit England sometime in the near future. That would be awesome. Take care my friend we love you here in good old blighty.
You would think that they would use stainless steel for the carb float bowls since that protective coating doesn’t last with today’s fuels.
They want to maximize profit, so they use the cheapest material possible.
If you look at all new equipment manufactures recommend anything stored more than 30 days should drained of fuel. THANK YOU FOR VIDIOS GOOD JOB
Have u had the gel analyzed? I believe it is sugar/starch
Fuel shut off and run dry. That's been working fine for me in my snowblower and garden tractor for years. I haven't even drained the fuel tanks. After seeing here that Seafoam isn't that great i am sorry i bought 2 or 3 cans when it was on sale. Some fresh fuel added to the tanks is all i have done when i put them back to use. Have always used some type of stabilizer. No problems. My Toro snowblower is from the late 1970's and has the original Tecumseh engine on it. I'm the second owner.
I'm up in southwest lower Michigan not too far from the shop. How much for one of the engines? I'll come pick it up.
I'm a firm believer in marvel mystery oil I've used it for years in everything I got
Just a question could the additive be bonding to the water and making the gel ??
I cant believe how long it took me to realize that these guys r being comedians.
I run stabilizer and mix it properly, no problems. Down south here with our humidity and bad gas it sours fast.
Great video
More important than starting is the condition of the bowls at 5 months. That is more closer to going through winter on lawn equipment.
Question is, if the gel is there, will nee fuel as it runs next season dissolve it or add to it? Lol.
So many experiments when just draining your carb or using non ethanol works. Former for those that cant get non ethanol from a pump and latter for those who can lol
Youve done so much and only people lookingnfor truth and nit confirmation will alpreciate the work you did.
Infound it!!! Wasnt added to the playlist lol
Taryl, we have non-ethanol fuel available here and i have started using it in all my gas powered (4 stroke) engines. Will this fuel last longer?
I believe that stuff is snake oil on the gel if it starts and runs but has gel in the bowl will running it break down the gel and clean up or not is there a additive that will clean it as long as it runs
Thanks for sharing buddy love watching have a wonderful Easter
I use 2 cycle mixing oil for winter storage,no problems
Taryl, surely your are aware that Startron when broken down is Start-RON as in Ronnie? Are you sure Ronnie didn't pull one over on you since it was the worst one?
Ronnie reminds me of my friend Darryl. We called him “Poison Jivy”. Poison for short.
RIP Darryl, miss ya bro.
Good call Ronnie remind me of my dad’s old friend Joe Ronald Cassini LOL
The question is, is Taryl Sta-bil. 😂
great video!
Great infor for lawn equipment. But people leaving generators filled should pay attention .....
I'm very disappointed in seafoam. But very interesting video. Thanks Taryl and keep up the good work and stay safe
Hey i think i read seafoam was originally made for 2 cycle outboard motor boats, they still use the same formula.
Just seems i read that somewhere. Not sure though.
Dont have that gel in norway since there is no ethanol in our gazzoline
19:42 It would be interesting to see how the Ethanol Shield would have performed if it was mixed properly. In the previous video in this series he mixed the treatment for this video at 1/2 oz per gallon when the bottle he was holding and pointed at said 1 oz per gallon for “storage”. Can we expect manufacturers claims to be accurate if we don’t mix the product to their specifications?
Probably all the snake oil provides more alcohol. I think the alcohol absorbs water and evaporates. Leaving you with water and gas that doesn't mix. By adding alcohol it makes water and gas mix instead of separating.
For long term storage, draining the system and a capful of oil in cylinder is best for me and my peace of mind
Any water removal from gas opinions,, does Mr funnel work ?
How full were the tanks
I wonder if the seasonal blends of gas would skew the results some. These started a lot easier, and fuel degradation was different.
You might be onto something... Often my gas can has gas a month or 2 old before I put in the lawnmower. The gas left over the winter might be 9 months old... Or "Summer blend".
I guess Gumout has a fuel inj and carb cleaner with (PEA or polyetheramine) for use with ethanol fuels now, I haven't tried any but I've been reading about it.
Well, scratch Sea Foam off the list.
It’s only gonna get worse with the 15% that’s coming…
Let’s go Brandon
I'm not surprised about the seafoam, that pretty much mirrors what another channel found. Fortnine did a fuel stabilizer test a while ago... I still use seafoam for cleaning purposes, but never fuel stabilization.
"I still use seafoam for cleaning purposes, but never fuel stabilization". Same here.
I run straight seafoam when I clean. Gonna try topping tyrals test. I have about 4 gallons of gas stored with stabil. Going to put it in my 127 and see if it held up.
I know it's over 10 years old.
Runs like a champ
I'd like to see this test done with trimmers and plastic fuel lines
Could be good test.
My neighbor swears by Sea Foam. I have some but I've never been able to get myself to use it lol. Then again, my non mowing "season" is usually less than 3 months. Cha, sometimes less than 2 lol.
Bravo! 👍👍
tyrel should i drain the gas tank and carb on my lawnmowers and generator for the winter
