thank you for this video. I've had to try and explain this so many times and there are so many people that think going from 89 to 93 is like adding nitro-methane to their gas tank.
"What fuel should you use for your car?" excellent question Scotty... Propane. It's 110octane and burns way cleaner than gas.

I worked in the oil/gasoline industry for 15 years. The rule of thumb is use the minimum grade of gas which prevents knocking (kinda like your car coughing all the time). If it knocks at regular grade, go to mid-grade. If it still knocks, go to premium. The "long term damage" this video talks about will happen to very few people because they never own their cars that long. If you do own a car that long, other mechanical problems will most likely be the bane of your existence well before these engine issues.
I own a 2017 Ford Edge. Bought it brand new. Not a high performance vehicle by any means. Until about six months ago, I was using 93 Octane...no knocking. But with gas prices soaring, I downgraded to 87 octane to save a few dollars and am now noticing the knocking mentioned in the video. Other than being noticeable and somewhat annoying, is the knocking going to cause any long term damage to my non-high performance vehicle engine? Or can I live with the knocking and still expect to get 150 - 200K miles on my engine (with regular service appointments, of course)? Thanks! I appreciate any advice.
@@jimsparaco4637 The answer to this, and most other questions involving gasoline and mechanical issues is "it depends." Not knowing how many miles you have on your Explorer now, I can't speculate on what its condition will be at 150K miles and how much you drive under what conditions. And I know enough about car manufacturing to know that not all engines are built equally - some engines for the same make/model car just perform worse (hence the word "lemon"). If I assuming you're planning on owning and driving this car for a long time, and you really are pressed for the extra cash for premium (who isn't these days?), then try a Plus grade gasoline and see if it works. Or, alternate fuelings with regular and premium and see if your car knocks. Or tweak the ratio of regular/premium fuelings. Oftentimes the occasional premium fill up is good enough. Of course, probably the easiest analogy is that, if you can afford it, it's like insurance. You're paying a little extra fee at the time to potentially avoid paying a lot down the road (again, assuming you own this car for a long time). Engine knock is not great long term for your car, but I've known cars that lasted many years with knocking and some that have developed problems earlier. It depends.
@@ishave1627 Awesome...thanks for your informative and prompt reply. Much appreciated.
No, just use whatever your manual says your engine requires.
@@reh3884 The manufacturer is always going to over-recommend the car requirements in the manual for both gasoline and oil change frequency. That is for liability reasons. In real life, it's different. My last 3 cars were a BMW and 2 Audi's. All were recommended to use Premium in the manual. In each case, I dropped down to Plus grade, with an occasional fill of regular. Zero problems with any knocking or engine damage after approximately 6-7 years with each car when I traded them in. But if you want to always pay for Premium, then that's your choice.
I always use Super Premium in cold weather. My hands don't get as cold when I put 20 bucks in.
Good one Stanley; I confess I had to blink a couple of times and read it again, but I got it.

For a short time I was a fuel tanker driver. Mid-grade is a mixture of regular and premium. Each gas station chain has their own mixture requirement. When I went to pick up a fuel load I'd have to mix a certain amount of each to get that required amount.
Makes sense. Why would you produce several different grades, if you can get the same effect by mixing the two in appropriate ratio? I noticed Sunoco stations have 4 grades of gasoline and I even saw some stations with 5 grades, but that was long time ago.
correct. I've been a fuel tanker driver for 26 years. In CA the mix is 50% of Reg and Prem to make Mid. Most gas stations mix it at the pump, few stations nowdays have a separate tank for Mid in that case we do the blending when loading (called splash loading).
I recently notice this. I got more gallons out another station and less at another.
That’s incredible 😮
Thank you for being straight forward and unbiased. I always thought higher octane meant more power but it has to do with avoid premature detonation in the engine cycle.
In the '80s is my buddies race cars we go down to the Avenue and pay $350 a gallon for 107 Octane and it made a difference but then again we're buying racing fuel
hmmm so to fix my nightly premature detonation it sounds like I'll have to fill myself up with some higher octane fuel.
Avoiding premature detonation = more power...
my high school sweetheart was, in fact, less than pleased with my premature detonation issues. this isn't about cars.
@@ilyas6875 Did this malfunction take place in the cylinder or the injectors? Asking for a friend! 🥴🥴
Fun fact, in WW2 German aircraft engines were designed for 60 octane fuel. US engines for 100 octane. This made the US planes faster and more maneuverable. The Germans eventually switched to 100 octane fuel, but as the engines were not changed they did not get as much out of it.

His voice is too annoying to listen to no matter what he has to say imho
Teacher? The man is a SCIENTIST!
My last 3 cars have called for mid grade including my current which is turbo. I've always used reg and never had knocking. 4 or 5 years ago my friend and I used a tuning system changing his car for different fuel grades and tracked our fuel mileage using 3 different grades on a long trip. We got slightly better fuel mileage in the higher grades, but it wasnt nearly a large enough increase to make up for the difference in price
I seem to get 3 extra miles per gallon using 91 octane in my Dodge Grand Caravan. It has a 283 hp 6 cyl. Noticeable improvement in performance on interstate highways on long trips!
Scotty, not sure if this was covered, but we have the "may contain 10% ethanol " stickers on our Canadian pumps. I also run a lot of small engines for yard work and motorcycle and off road vehicles. There are about 4 or 5 distributors including Costco Canada that their premium does NOT contain ethanol. That's what I use in engines that may not get a big turnover in fuel, like a generator. I have cleaned so many carbs that are just plugged solid from old fuel with ethanol. It also attracts moisture and contributes to rusty tanks on motorcycles and other engines if they are not used regularly. If I use premium with no ethanol, I don't need a fuel stabilizer on engines sitting till spring etc.
Ethanol is garbage.
I'm with ya there. Premium here generally means no ethanol we did an experiment with our 07 sierra truck that will also run e85 fuel that isn't available in Canada. Non the less we would generally get after some time using regular fuel we would get a trouble code and reduced power eventually I would have to clean the throttle body. We switched to premium and have not had that issue so far it's been two years we've had the truck for five we also get better fuel mileage so now I always run premium and as you stated premium for the toys always
True, but it keeps the Political Donators happy who control our Congress to keep mandating ethanol which produces LESS POWER and burns MORE FUEL, making them RICHER!
Marty, I’ve heard of ethanol clogging up small engines!! So what is it doing to our vehicles?
You see I had this beautiful 2004 Lexus ES 330! and my husband said, it doesn’t make a difference! But it does! I don’t Know why they’re letting them sell us this garbage ethanol that will eventually clog/seize our engines in the long run. From now on, it’s Super for my new car. Thank You
@@gloriacedeno.2737 Car engines have very different designs from most small engines in tools or some motorcycles. The rest of the car (fuel lines, seals, etc.) is also designed with it in mind. Those smaller engines are often using very old designs. For example, you may find a carburetor in a new snow blower or weed whacker. You won't find that in new cars nor used cars going back many years. Also, unless you don't drive your car at all, fuel probably doesn't sit in it for more than half a year at a time. That's where a lot of problems come in.
This needs to be running in the background in DMVs!
Agree! Any Scotty K video (or audio) would suffice in the background at the DMV.

@@JamesJohnson-eg6yd especially when compared to Scotty Kilmer!😉
Here in Colorado, the gas companies rip us off by calling 85 octane “regular” and 87 octane “midgrade”. My car requires 87 octane, so that’s what I buy, but it costs me about 30 cents per gallon more than the so-called “regular”.
There is a lot of content about it. In short -- 85 in Colorado is no different from 87 elsewhere. They just label it differently (similarly how Regular in the US is no different from Regular in Europe despite a very different number)
Because Colorado is run by idiots
I thought it has to do with elevation which is why 85 is sufficient whereas 87 would be used at lower elevations.
Is that right? Seems like you would need higher octane in higher elevation because the lower atmospheric pressure would make it easier to combust, but maybe atmospheric pressure doesn’t matter inside of an engine.
I’ve wondered about this, myself since moving to Colorado. I think we need Scotty to weigh in here; he’s about the only one I trust on matters such as this.
Mon and Ron
Scotty, we use Motor and Research method when blending gasoline in the US. Also the RVP will change depending on the season.
We would set the knock motors with a known proto fuel to compare knocks from the blending sample and adjust the blend recipe to make the octane and vapor pressure.
Been making gasoline final product for 20 years. We used to make 93 premium and 93 RFG when MTBE was legal to use.
I grew up knowing nothing about cars before I found your channel. Thank you for the videos, Scotty!
Good vehicular education at the cost of Toyota propaganda.

If you've been listening to this guy, you still don't
Thank you Scotty, I'm 70yrs old and have been asking these questions most of my life. I'm getting ready to transfer to a gas vehicle from diesel. I never knew what the E-85 actually meant. I will keep this video and use this information as I transition to a regular vehicle.
God bless.
@Mark Codiroli I made a Typo. E-85. I will pay attention now to see what's most available at gas stations. I prefer not to use the E-85.
E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging from 51% to 83%. Wikipedia. Unless your specifically says in the owners manual you can use it, do not use it. My experience with a “FLEX fuel” Ford Vehicle was that I got half the fuel mileage on E-85 than on regular gasoline and the E-85 was not 50% of the cost of the regular gas offered at the same station...so it was a bad deal.
I've always said E85 waste of food.
why? you're gonna be disappointed in your mileage, bigtime. I haven't driven a gasser in 30 years.
I use your videos for personal car questions all the time but i thought i would give this a shot because i been reading about gas alot recently to stay informed.
I was very impressed with how organized and easy to digest all this info was. I liked the use of plane terms for us laymen and ill likely send this around to some folks i know.
Feel like I am back in class. Great going Scotty, explaining how octane works, most people do not know this.

I said the same thing. 🤣🤣🤣
I haul diesel and gasoline for a Co Op and go to the pipeline on a regular basis. There are 3 grades of gasoline, A grade (910ctane), V grade (83 Octane), and E grade (Ethanol). In order to get the 87 octane you see at the pumps there are 2 ways, a 50/50 blend of A grade and V grade or a 90/10 blend of V grade and E grade. 89 octane at the pumps would be a 75/25 blend of A grade and V grade or an 85/15 blend of V grade and E grade. 93 octane at the pumps is your A grade (91) with an additive to boost the octane rating. Not all gas is created equal, but it all comes from the same pipeline in your area. If you go across the street to get gas because you think the other gas station on the other corner has crappy gas, wrong. I can guarantee you it came from the same pipeline, the difference is the detergents and other additives the supplier put into the gas when they loaded it on the truck. Each supplier has their own formula of additives that they use in their gasoline, and this is all mixed in while being loaded onto the truck to go get delivered to your local gas station. There is one thing that will stop me from getting gas at a location, and that is if I see the truck there making a delivery. It's because when they unload into the underground tanks, they stir up all the garbage in the tanks, and you don't want to pump that into your car. Sure, there's a filter on the pump, but they don't catch everything, and it will eventually plug up your fuel filter on your car causing you issues.
I worked at a gas station for a while, third shift so I'd often be there to assist with refills from the truck but never knew that "fresh" gas would stir up the residue in the reservoir. Makes sense, thanks for the tip.
Thank you for the tip! And Merry Christmas and Happy Holidays!
I talked to a tanker driver at the pumps once,he told me the stations with the ""blue"" caps over the fillers on the ground are pure mid grade..The stations with only "red and yellow"" caps over the fillers on the ground are mixed ..red(high grade) and yellow(low grade) to make mid grade.
@@enochrry6024 He could be right, but I don't know of any midgrade gasoline, just the 2 grades A and V, then throw ethanol into the mix. I don't deliver to gas stations, just to our own Co Op and we only have one customer that actually has underground tanks. I do know that they can do some fuel blending from their underground tanks, our one customer does it with their diesel during the winter blending #1 and #2 diesel for the plow trucks.
@@mfraze8753 ..I may be wrong,but I think the driver meant the pure mid-grade is mixed at the ""refinery"" to go straight in the tanks in the ground at certain stations(blue caps)..All the rest are mixed at the stations ""high"" and ""low"" to make mid-grade..I think.
You’ve never heard him so calm because he’s doing a documentary. Unlike when working on a car with your hands and explaining to people on how to do what he’s doing
This is very informative.
I used to live in the Clear Lake Area near the Johnson Space Center in Houston and would sometimes have to go to La Grange for work. When I had to go, I'd fill my '64 International C-900 pickup with gas the night before. Then, when returning, I would not have enough to make it back to Clear Lake and so I had to refuel on the west side of Houston. That was with regular gas.
For some reason one day, I fueled with premium gas instead and found that I could make it all the way back to Clear Lake and had enough for regular driving for a day or two. So I started doing this regularly and enjoyed not having to fill up with gas on the west side of Houston.
You wouldn't think that a '64 International pickup would need premium gas, but it sure helped the gas mileage.
I bet that premium gas didn't have ethanol in it
@@newguy3588 Probably not. That was in the 1980s.
I had a truck that had over 150K miles on it, when it started pinging, and I found that using higher octane gas prevented this.
Thanks for the info! Just stumbled into this video and delighted I did.
Thanks for the straightforward info. We appreciate it!
I’ve seen 85, 87, 89,, 91, 93, and 95 octane at gas stations--never all at the same time; never more than three options.
Well done Scotty! 👍

@@agoogleuser4443me too.
My 2017 VW Passat 1.8T only requires 87 octane. But I noticed a definite power increase when running 93 octane.
Especially the smaller the engine. I also notice more power with the e3 spark plugs in my Honda Civic.
Period
Same we use 98
All forced induction engines do better with higher octane.
I know most people will laugh...but I swear that my 04 Pontiac montana gets better gas mileage when I put in higher octane. I cam fill a tank with higher and it will last darn near two weeks. Lower octane and I am back at the friggin pump in less than one week. I pretty much drive the same every week. So....who knows...lol

Very nice video, great explanations and superb animations. Good work.
Great video Scotty your videos are always helpful informative this one here really taught me a lot
It's amazing how many so called mechanics these days don't understand something this simple. Thank you for this excellent video.
Scotty, I learned many things from this video. I enjoyed the history about Ford and it's "flex-fuel" capabilities.
Thanks for the education. I’ve a Focus RS that I’m supposed to use premium octane which I’ve done 100% of the time. It’s validating to learn what I only kinda knew
This makes sense. I found my old car would run noticably more efficient with mid grade while doing long trips, but not on short drives. Now I know why.
Save you 10 minutes: use whatever your owner’s manual requires.
thank you
exactly...so many ignore their manual and listen to internet "experts".
Not everyone has a manual and they have to listen to other people's recommendations. I'm one. I've had 6 different vehicles so far and never a manual. I was taught that, unless you have a high end sports car or diesel truck, always use the lowest grade fuel unless you want throw your money away.
Came here for this 🙌
@@Moraenil you can look up the manual of any car online for free.
I was taught by my mother, a Chemist who worked for Union Oil, that you would get better gas mileage from higher Octane (pre ethanol) gasoline, but it was not worth the price difference.
I’m not a chemist,but I know she’s correct….i own 3 vehicles and what I’ve noticed is this…When I use higher octane fuel I get greater gas mileage every single time
Thanks for confirming what I suspected about the octane levels.
I've learned to use manufacturer recommended gas and oil only...I have a 2017 prius that calls for regular only and 0/20 oil. The reality is that cam phasors and active lifters use oil viscocity to help determine valve timing...changing either can be problematic....
You should be selecting your oil mainly depending on your environment.
@@pinionification ..Yes,specially with temperatures reaching 105 in the summer in the south.
I love this calm version of Scotty's video. so much easier for me to keep up with and to understand thank you
I bought by 93 Explorer new way back when. The manual recommended regular gas, the lowest octane, so that's what I put in it. During the first few months I noticed a rattle from the engine when accelerating. Nobody could figure it out. Then I realized that whenever I used premium gas, the rattle disappeared. With mid-range gas, the rattle was only present during unusually hard acceleration. I ended up settling on mid-grade on everything I drove, and drove reasonably. Never had rattling problems again.
my car suggests premium and it's turbo charged so I'll never put anything different in it lol
I switched to premium on a whim several years ago on both of my old cars. All of a sudden I realized my old engines had been knocking slightly but I didn't recognize it. I just thought they were old engines that didn't run like they used to. Now they run great. I use only premium now.
Thanks for addressing this often discussed issue!
85 octane is available at stations in high altitude areas--equal to 87 in lower areas.
Yes it is but most car manufacturers don’t want you to use regular 85 octane
@midnitesquirldog1 I remember Sunoco ultra 95
I lost two miles per gallon in my V-10 engine when I stopped being able to get straight gasoline and had to start getting gasohol. I was only getting 16 mpg on straight gas as it was. I also lost some performance too.
Dear Scotty, Sir, thank you for helping people to better understand and know so much.
Very informative. I learned more about my car watching this video. Thank you.

Actually the US uses the research octane number (the ability to resist detonation at low rpm) + the market octane number (the ability to resist detonation at high rpm) / 2, or the R+M/2 rating.
Love Scotty’s videos! He’s helped me fix my car a couple dozen times
A few facts about ethanol in fuel:
1. If you don't drive your car very often (as in, standing still for weeks at a time) the ethanol starts to attract water from the air. This water can then cause corrosion in your tank.
2. In Europe all fuels containing less than 5% ethanol are marked as E5. Chances are it'll actually have 0% ethanol.
3. In older cars the ethanol can dissolve seals and fuel lines so check before filling up with E10.
Finally, some observations: in my own car I've noticed a 5% reduction in fuel economy when using E10. I did not see any change in engine performance.
You saw a reduction in fuel economy because ethanol fuel has less potential energy and (if I remember correctly) a higher oxygen content than regular gas for the same volume of liquid. This means the computer has to compensate by injecting longer, or more fuel, compared to plain gasoline to get the same amount of work (power) out of the engine.
I have heard some of the classic car collectors refuse to use ethanol gas because it will eventually gunk up the engine. Anyone have thoughts on this? I've also heard it's bad for lawn mowers. Any truth to that?
I started putting 91 or 92 octane in my supposedly 87 octane car 36 months ago (Mobil, Chevron) but now I use ARCO top-tier 91 exclusively. I get 24 mpg hiway like the window sticker says I should have been getting all along, but hadn't. Same results for the gf's Explorer, friend's Camry, daughter's Malibu, friend's Jeep, other friend's F150. Explorer went from 15.7 mpg to 20.5 mpg (mpg shows on the dash). MPG improvement aside - performance on all vehicle 'greatly improved, engines run much smoother and easier startups.
LOVE THESE SPECIALS, KEEP IT UO SCOTTY, BEST ALWAYS!!!
One thing you missed here mate. Some cars have a recommendation for X octane, which is just fine. However, if that car is able to actually advance the timing toward MBT with a higher octane fuel, you are absolutely better off (power wise) to be running a higher than recommended octane fuel, IF the car can’t reach MBT within the higher octane fuel. The simple truth in that instance is that the manufacturer is recommending a MINIMUM octane rating rather than a maximum.
Thank you Scotty,
Very interested and educated video
Thanks for this Scotty. Been a long time since CZcams sent me a notification for one of your videos.
Amazing video Scotty! I can see alot of work went into this one!
I use 93 octane in my 20 year old Toyota Tacoma. Every time I have to use 87 octane the check engine light comes on. When I use 93 the check engine light never comes on. Plus each time I used 87 octane I would always have water coming out of the tail pipe.
Sounds like the intake system needs cleaning. I’m wondering if gumout will actually solve the problem. I had an old car that would give me a few warnings that would go away when using 89, but they also went away after putting extra additives in the gas and went top tier for a while. A mechanic told me I needed a fuel induction service the first time I went in, but not the second time.
One of the potential reasons is carbon buildup in the cylinders. Now you need more knock resistance.
Also agree sounds like you need some sort of system cleaning because of carbon build up.
Caveat, at the pump you might have the option between fuels blended with corn crap (ethanol) and those without. If you have that option of no corn crap it is almost only available in the premium grade.
Detonation is a twenty ton hammer blow to the top of the piston and the ping is the crank bearings contacting the crankshaft because the oil film is forced aside by the force applied to the piston. This at least was the explanation Champion spark plug school gave in 1972!
Thank You Scotty for this video
I discovered you Scotty b/c I had a horrible experience at Firestone getting my car checked; ck engine light was on they wanted to charge me 100.00 to check. You should be teaching this stuff to high schoolers. I learned nothing about cars from anyone when I was a kid. I am empowered now my friend! Now I can’t stop watching you; I love you!
Literally no one charges $100 for a check engine light.
@@higgy82 yes they do, every shop I’ve ever worked at charged at least $99. Because we had better scan tools than the part stores.
@@fallenhero99
So you openly admit you worked at scam shops?
@@higgy82 They do!A few years ago Courtesy-Chevrolet charged $99.00 for check a light in my Buick.
say no and call around and get a ob2 reader
Every gas vehicle made since 2006 has a knock sensor so you can use regular or premium gas without engine damage. The caveat is engine hp and fuel economy: Car & Driver tested four high performance vehicles in 2019, they found high octane gas(93) increased hp and fuel economy
8:29 : Ethanol isn't as "renewable" or "carbon neutral" as its proponents like to claim. Planting the corn, harvesting the corn, turning the corn into cornstarch, turning the cornstarch into corn syrup, fermenting the corn syrup into ethanol -- all of these steps consume energy. Some studies even go so far as to state that it takes MORE energy to make 1 gallon of ethanol than the chemical energy contained in 1 gallon of ethanol!
Also, without government subsidies, the prices would be way higher. I've seen some videos comparing mpg of straight gas vs ethanol gas and straight gas wins every time.
@@Llew70: That's not really a fair comparison. It's well known that it takes 1.7 gallons of ethanol to equal the fuel power of 1.0 gallons of gasoline, so we'd expect a gasoline-powered car to get 1.7x the miles *per gallon* of the same car running on methanol.
The real issue isn't the MPG, it's the COST of 1.7 gallons of ethanol, vs. the cost of 1.0 gallons of gasoline.
These videos are the best. Thank you Scotty!
I live in the western USA, where we have garbage 85 octane for regular gasoline. When traveling through the midwest, we fueled up with 10% ethanol gasoline. The ethanol must've cleaned grime off of things in the tank or fuel line, as we ended up with a clogged fuel filter. It's happened twice during trips to the midwest, so we always keep a spare fuel filter with us and we immediately know what the problem is if we encounter engine trouble on those trips.
Sometimes you just get gas from a station that has a lot of crap in it, and it clogs your fuel filter. My son and I changed our fuel filters right before we both drove up North a few hours to stay with a friend for a while. I stopped for gas before him so we ended up going to different gas stations once during the trip. When we arrived he said his car was running bad and was hard to start. We pulled his fuel filter and poured a bunch of really fine black something out on a paper towel. I pulled my filter just to show him it did not have that inside. All it takes sometimes is one bad gas fill-up and you need a new filter.
@@ezralord4901 I have been told that it’s not a good idea to buy gas when there’s a fuel truck there at the station filling the underground tanks . It stirs up debris in the tanks and that gets into your fuel lines and can mess up the engine.
@@glennso47 You are very correct. My Grandfather told me that too, and I didn't listen to him once... it did make me end up rebuilding my carb because of all of the trash I got in the gas that fill up (this was back in the 80s), but to this day I will not get gas at a station that is getting their gas truck.
I'm glad to see your channel grow so much bro
Very informative, thank you for the great video!!
What a lot of helpful, factual information! With a high WPM, Scotty's fast talking really covers the whole gamut. Thank you, sir!
This video is relatable because I just put fuel in my car
lol
Same. Stay safe, stay blessed.
That's because the GPS sensors in your phone knew you had been at the gas station , and since Google has access to all the data in your phone and they also own Y.T , you get the recommendation for this video. 😳
@@drinkthekoolaidkids I didn’t gps the gas station. Are you saying my location is turned on sending an alert to all online services?? Stay safe, stay blessed.
@@telisah9611 bingo !
Nice explanation! Thanks.
I always believed that the car companies and the gas companies tricked people in to paying more for gas. I own a 2004 V8 Tahoe and have been putting in 87 octane for over 200k miles and never had any engine trouble and still runs great. Besides normal tune ups and maintenance. Maybe I’m just lucky. Maybe on luxury cars Corvette and Lamborghini this makes sense. Just stating my personal experience.
I like the power point style and whatever vocal style editing is a nice change for pace even though I love scottys upbeat personally
Keep these up Scotty, loves the informational vids u make!
Actually octane and grade are different depending on where you live. Where I live, 85 is regular, 87 is midgrade, and 91 is premium. They are specially formulated for areas that are dry, or humid, or high altitude.
Utah has 85,87,88,89 and 91. I use 87 or 88 whichever is available in top tier gas. My car recommends 87 so that's what it gets.
Thank you for putting out a nice calm informative video. So many people believe that higher octane means higher power. Your explanation was right on and I appreciate it.
In a way, it does. Anti-knock sensors will retard timing in your car when the detect pinging...which lowers the power.
Depends entirely on the engine. Engines from the "Bad Old Days" ran on something like 106 octane leaded, this 87 octane horse piss they call gas now, yeah, it hurts your performance (in those engines). Some 110 avgas I hear would be wonderful, if not apparently completely illegal.
@@johnsansker7064 I know exactly what you mean. I had to put so many additives in my fuel just to keep my old Chrysler running. Those engines from the fifties and sixties didn't hardly run on this junk we have at the pumps anymore.
@@1stupidfish In the process of buying a 1966 F100 with a 352, will have to look in to what will be needed to keep it happy.
@@johnsansker7064 in the 70s we would take 5 gallon cans to the local airport and get fuel for our "boat"
Scotty fuels the auto traveling public with knowledge.
I have little idea what he just said.
I drive a diesel SUV so it doesn't matter to me.
I get about 6 kilometres a litre.
Less on the highway.
About 1000 kms a tank.
this will confuse people they just want to know how to watch tv, text, and keep their butts warm while the cars self drive and park
You know what I like more than sports cars? KNOWLEDGE.
Hey Scotty, You need to stop calling people stupid some people just don't know about this kind of stuff. Maybe one day everyone can be as smart as you.
Outstanding videos, keep em' coming...
Thanks I’ve always wanted to know the run down on the different types
Thank you Scott. All the best brother
Scotty you are a national treasure your worth your weight in gold
National?? He's international, I live in Mexico
@@carlos3m13 I stand corrected international treasure
wish he were my mechanic - I'd drive old cars instead of buying new every 100k.
You taught me more than what I came to watch and it was a great need because in a detailed learned and the animations def helped out
Gotta be the best explanation I've heard.
