After reviewing all the comments, I have to add that if you do try to use a lower octane fuel, you may need to double check there is no 'knocking' in the engine not just audibly but with an ODBII reader. The reader will record every single instance of a knock or 'backfire'. While using lower octane once to test it out is unlikely to cause engine damage, using it continuously with the engine knocking could damage the engine. Hence, if you do this, you really need to know what you are doing. Also, it probably doesn't work so well with engines with turbos. Turbo engines work with increase pressure and so a lower octane will cause it to knock. Depending on the engine, it may or may not be able to compensate.

The first time, people could, just add 1/4 of regular gas when the tank is with 1/8. If the car run perfect can add additional 1/4 of gas. If something go wrong you can mix a 1/2 with a premium gas. But I use in all my new cars and never had a issue (Mustang, Fusion, Miata, etc).

Back in the day, I had a car that was intended for lower octane fuel, but I fully advanced the ignition so that it would run on premium. Although the fuel cost was higher, it was offset by the improved efficiency of the motor. This was a fuel injected vehicle, but it used an OBD-1 system that wasn't equipped with a knock sensor.

Back in the 80's it was common to hear knocking at 87, so I used 93 octane but it was only $.20 a gallon more back then. Today the quality at 87 is better because the government made them clean up the gas with detergent I was told in about 2011. I bought a used 99 Lexus that required premium in 2018. I tried 93 and 87 because of the roughly $.60 difference in Illinois today and I notice no knocking and the gas mileage was identical. I have put 60,000 miles on it in 4 years and its still running well at 271,000 miles on 87. Sometimes I put a booster in the tank but I also don't try to dog it while driving as well. Just my experience.

Thank you so much for your advice.

As always, interesting!!

Would only do this if you have a naturally aspirated vehicle with no turbo. The higher the octane, the more resistant the gas mixture is to pre-ignition, especially when the turbo is forcing air (and hot air at that) into the combustion chambers. Modern engine management computers can retard timing to limit (but not necessarily stop all) pre-ignition, which is harmful to your engine especially at full boost and high RPMs, but doing so will cause a rise in exhaust gas temperatures which will cause the turbo to heat up more, and since the turbo is oil cooled, the oil temperatures will go up locally, and if the engine is shut off suddenly, the turbo can "cook" the oil leading to a build up of junk in the lines, causing a oil starvation and turbo death. The remedy is to use the recommended octane rating for your car, at least if you have a Turbo and it recommends premium. Not to mention the reduction in mileage with the turbo will be especially noticeable with regular gas.

When I try to do the mpg calculation, I find that it varies by a few mpg even without changing the octane rating. So you really have to be super careful in this measurement. For example, you have to make sure the driving style and amount of freeway/streets is roughly equivalent. Also, how are you measure the amount of gas you used? Use it up, then fill it to the top, and that is what you used? One pump may stop earlier than another so you should also use the same exact pump at the same gas station with the seal of the pump in the exact same way.

Owned a 2012 volkswagen cc 2.0T used reg gas a few times on it and it did nothing.

My recommends 91 octane. I tried 87 octane once, and the check engine light came on while i was cruising on the highway. I wasnt even putting the engine on load as i was driving with low rpm.

I have a 1997 Skyline GTR R33 modified from Japan with a standalone ECU. They likely tuned the car on their premium gas over there which is 100 ron, about our 95 aki here in the states. Me being an idiot, just ran it with 93 the first time I filled up, which is the highest I get near my area. I took it on the highway, and maybe only pressed down to half the gas pedal, but still within boost, and my knock meter on my power FC spiked to over 100! Needless to say, I garaged the car right away. It's been in storage since, and I need to retune the car on our 93. Might run with Torco octane booster temporarily. Heard they are the best and I can get 100 when mixed with the 93.

My 2006 Toyota Highlander Hybrid was knocking with regular gas, then stopped knocking with premium gas. ? Which type of gasoline should I use for my 2006 Toyota Highlander Hybrid Limited 4WD-i? ? “Premium Unleaded” is recommended in the Owner’s Manual, page 302, Fuel Selection: in the Octane Rating: 87 (Research Octane Number 91) or higher. For improved vehicle performance, premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher is recommended. ? “Regular Unleaded” is recommended in the VIN Fuel Type section

How the computer can adjust the ignition while using a lower octane gas, when even from your words, the lower octane gas will ignite spontaneously under some lower pressure than higher octane mixture?!

Most cars are meant to run on 87 if you're car requires 91 there will be a sticker on the gas cap. Putting 87 in a 91 car wont cause immediate damage although over time there could be problems and the cars performance will be slightly worse. Often times 91 gas is actually a mixture of 87 and 91 because the gas station orders too much 87 and the manager says throw the extra in the premium tank. If you want to take good care of you're engine using top tier gas is better than using premium.

At the moment I am driving a car and using a premium grade. Because it uses slightly less gasoline and thus it pollutes slightly less. That and because I really don't think my car even has a ping detector. At one time we had a Davies brothers station in my area and they charged 15 cents more than the price of regular, kind of missing dealing with honest oil companies.

Here in the uk we only have one type of petrol now and that's octane 95 with ethanol which they call E10. Which is £6.75 a gallon which is $8.90 a gallon crazy prices.

Thank you

Also Mobil gas seems to work the best for me and I have done deliveries part time since 1988.

How many miles did you put on your porsche... what's total mileage Now ?

FYI it’s not just turbocharged engines but supercharged engines also. Rule of thumb is to do whatever the manufacturer says is ok as in recent years some engines are under higher compression so they require 93 and manufacturers state 91 is ok BUT nothing lower. Your statement is current 20 years ago when they pushed manufacturers to require all new cars sold run on 87 but they quickly backed down due to all the push back so if the manufacturer says 91/93 is required then you must run it or you could void your warranty and or damage the engine. Do what manufacturers require only. Never do what someone may say is ok.

I’d have to disagree with you Mr. Bush lol. I used to do Uber eats with a 2004 Acura TL which required 91 grade gas. Although, the engine worked fine with lower grade gas, I did notice an astonishing dip in my mpg performance! I went from 19-22 city mpg with 91+, to 12-15mpg with 87. It was horrendous

There’s a bunch of videos on why you should use high octane and there’s a bunch a bunch of videos on why you don’t need it. What to do 🤔

Every car sold in America needs to work with 87 octane gasoline by law. I have a 2021 BMW, 2020 Acura, had 2018 BMW, a bunch of turbo GTIs / GLIs. All work fine with regular due to modern electronics (knock sensors retarding timing). They do produce about 10% less power and maybe slightly more turbo lag on regular (very hard to notice). The most change in MPG is maybe 1 to 2 MPG, if any - but it’s hard to tell. Depends on the conditions. Winter driving seemingly no change. Hot summer, you might have dump more fuel in for cylinder cooling and less dense air. Turbo charged engines benefit from the use of higher octane (counterintuitively the octane rating just means it’s resistance to detonation) for mainly power. Why is this important? Turbo charged engines are high compression. The more they can compress the fuel the better the explosion is and the more power they can make off of each piston stroke. 93 octane fuel is more expensive due to a lesser extent the cost of the extra additive package (including the octane booster - all they do is take regular gasoline, we do not refine 93 octane in the USA and add additives) and to a major extent MARKETING. In Europe, their “regular” gas is higher octane to begin with. Last, Ford Motor Company and few other car companies started lobbying oil companies and the DOT to make “premium” higher octane fuel the only fuel in the USA. They argued that modern high compression engines all benefit from it from a power to engine size standpoint, and therefore you could squeeze out more power from a smaller displacement engine.

@BeatTheBush

2 жыл бұрын

Didn't know about this law. Do you know where I can find it? Let me paraphrase the last part from my understanding: While energy density in the fuel is roughly the same, higher compression means smaller engine size. The smaller the size, the less the engine weighs and likely the less inertia in the moving parts. So higher octane is indeed slightly more efficient.

Yes I'm Asian living in CA, and I always use the cheapest gasoline octane 87 and finding the cheapest gas station so that I could have the extra money to invest elsewhere. I'm not into cars because they depreciate in value a lot as time goes by.

Maybe it's ok to do that on a car like Lexus but would I risk it for a car like BMW or Porsche? NOOOOO way.

I stopped watching the second he started dishing out fake, manipulative information.

I make nothing if you buy 87 or 91, no motive.

If it is rated for premium, put in premium. You can easily damage your engine if you put a lower grade fuel in. Not worth the risk at all. Your engine can protect itself somewhat by altering ignition timing but this is not an indication that it can run on whatever fuel you feel like. I know gas is expensive but if you are hurting so bad you need to put regular in your premium fuelled engine, you cannot afford your vehicle. Period.

You can check if it knocks via the OBDII interface to be sure.

Hey man this is super random, but there’s someone posing as you on instagram, i think they’re trying to scam people FYI.

Don't do this guy's stick with what your owners manual tells you Your car was built this way for a reason like he said it can cause your engine to knock it can screw your timing up it can burn out sensors it can even void your warranty and you will get way better gas mileage and power out of running the gas your car is designed

As an engineer aren’t you obligated to support the engineer who designed the engine to accept a particular octane.

Sometimes, things are over engineered and what you see as a recommendation to the layman user is almost always an over simplification.
