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.

[@jimsparaco4637]

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.

[@ishave1627]

@@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.

@@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.

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.

[@pawelzielinski1398]

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.

[@whiskeymike8810]

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).

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

[@Labyrnthdom]

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.

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”.

[@AntonShmakov0]

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)

[@dragons_red]

Because Colorado is run by idiots

[@seananderson5334]

I thought it has to do with elevation which is why 85 is sufficient whereas 87 would be used at lower elevations.

[@spencercase5370]

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.

[@jedcook875]

[@martymartian9820]

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.

[@jazzyjace1]

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

[@khiem1939]

[@5467nick]

@@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.

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.

[@mattrhoades9487]

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.

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 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.

Great another class!! I hope your enjoying your trip visiting your family. Take time off to enjoy

[@scottykilmer]

so far yes, and thank you!

[@INvertPb4Life]

Keep these up Scotty, loves the informational vids u make!

[@jesm1194]

Gotta be the best explanation I've heard.

[@frisbee544]

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.

[@kevindarroch7332]

Dear Scotty, Sir, thank you for helping people to better understand and know so much.

[@burkeyatm]

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.

[@microsnook3]

Wish you would have went into the deal about the 85 octane at higher elevations. With and without MAF sensor, etc. Thank you for this.

[@michaelmounts1269]

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....

[@pinionification]

You should be selecting your oil mainly depending on your environment.

Good Wednesday evening you Scotty, hope you and your family are doing well. I've always wondered about the different grades of gas but never had the time to check it out now I do thank you stay safe and happy 🙌🧰👍🍺

[@LingoENT]

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

[@kenhart5259]

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.

[@pramponi]

Best explanation of octane I've seen.

[@jefflebowski918]

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

[@garrettsmith8591]

Very interesting and informative video, thank you Scotty

[@MARfilms]

Scotty, the mechanic, the machinist, the technician, the mechanical & chemical engineer, the physicist. All joking aside, Scotty has shown me a lot and has passed on solid advise and information. Also as a Mechanical Engineer, he explained thing that I remember learning about, but shows the real world applications better then most of my professors ever did, lol.

[@mikemcnamara9878]

My 2017 VW Passat 1.8T only requires 87 octane. But I noticed a definite power increase when running 93 octane.

[@asappestcontrol1250]

Especially the smaller the engine. I also notice more power with the e3 spark plugs in my Honda Civic.

[@christopherjones512]

Period

[@closertothetruth9209]

Same we use 98

[@RayleighCriterion]

All forced induction engines do better with higher octane.

[@PatriciaFerenz]

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

[@josephturberg3014]

[@Bronco46tube]

[@harolddouglas4057]

85 octane is available at stations in high altitude areas--equal to 87 in lower areas.

[@sciatl2505]

Yes it is but most car manufacturers don’t want you to use regular 85 octane

[@sciatl2505]

@midnitesquirldog1 I remember Sunoco ultra 95

[@larryray3178]

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.

[@whiteknightcat]

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.

[@Blahsheep]

my car suggests premium and it's turbo charged so I'll never put anything different in it lol

[@kl0wnkiller912]

I have two cars. My weekend toy is a 2014 CTS-V Coupe and as a supercharged car it needs 95 octane minimum to avoid engine damage. My daily driver is a 99 Mazda Protege with a 1.6L engine. This engine can run on regular just fine but running it on premium makes a NOTICIBLE power increase. Some manufacturers allow using regular to attract buyers but the engines are quite capable of running better if you want to pay for the more expensive premium.

The corn being harvested in this video was sweet corn sold in the grocery store, not #2 yellow corn which is converted into ethanol. love your vids Scotty keep up the good work

Interesting video. I'm in Australia. The noise you call pre ignition we call pinging. One of my cars is a 63 Impala with 327 V8, I have to use premium in this car ,otherwise it gets pinging. I've always been told can't use Ethanol fuel in these old carburettor cars because the Ethanol damages the carburettor and rubber hoses .
