My ‘02 WRX only drinks premium. Gave it regular one time after whichever superstorm that was when we had gas lines. It drove OK but I went right back to premium.

It’s a function of the engine’s design. Using a lesser grade than required can destroy your engine. Seriously.

Well, it is marketing, even though they are different octanes. The trick is that most cars are designed to use the lower octane gas, and if you put the higher octane stuff in, it can damage the engine. So the idiots that buy the “premium” stuff are probably screwing themselves.

We used 115/145 “purple gas” in the T-28 trainers (1977-78) at Pensacola. I used to love walking from the BOQ to the flight line early morning and the flights started taking off. It was like a scene right out of a WWII movie with the big radial engines in the T-28s rumbling and a long orange/blue flame coming out of the exhaust stacks.

Ethanol is not the only possible product of distillation.

True 'dat. Methanol is also a possibility. Distilling gasoline (very flammable liquid) is very very dangerous. Don't try this at home, kids.

The difference is the tendency toward preignition. High octane gas is harder to ignite than lower octane. The low octane wotks well in a lower compression engine because the low compression doesn’t raise the temperature of the fule air mixture to the point where it will ignite. As compression rises, the temperature of the fuel air mix rises, increasing the risk of preignition. Higher octane gas reduces that risk, making it far better fuel for high compression engines.

Untrue. It depends on the octane requirements of the engine. Generally speaking, 91 octane in an engine designed for 87 will be less efficient, have lower power and will get worse gas mileage.

I have a 2002 f350 super duty that knocks VIOLENTLY if I don’t put in 93 octane. Gotta be 93. With lower octane the knocking becomes progressively worse. At 93 it is nonexistant.

*******
That is only true if your car requires premium.... putting regular in a car that needs premium forces the computer to retard timing to avoid knock which reduces mileage. Just put into it what the owners manual says...

I used to use Sunoco 104 Octane in my 1973 Honda K-3 750.

A friend of mine’s dad had a ‘52 Chrysler.

**********************************************
My dad had a ‘52 Dodge...same transmission; I think it was called Fluid-Drive. Stick shift, so began in low then used clutch to shift stick into drive.

Back to thread topic... I had a ‘82 280ZX that began running rough. Dropped it with a mechanic on way to work and asked him to check out carb, igniters, etc. Went back after work and he said he didn’t do anything, and would save me lots of money. .....Followed his advise and stopped at a convenience store on the way home. Bought a pint of rubbing alcohol for about 30 cents and poured in my gas tank, which was about half full. .....I’d only driven a couple of blocks when the engine began to purr. The alcohol burned much hotter and cleared out the carbon buildup on the igniters and I never had another problem.

“The higher the octane, the better the gas mileage”

FALSE. The higher the octane rating, the greater the resistance to detonation (pinging).

My wife’s BMW required the highest octane. I didn’t know that. I put in the lowest octane. I complained that there was a delay when I stepped on the gas. She reported that to her BMW salesperson. He immediately knew what the problem was. When I started putting in the highest octane the problem disappeared. The owner’s manual usually gets it right. Most people don’t read it.

Yep - my Mercedes has a turbo and requires minimum 91 octane - the sales rep said he used 89 octane in his if from a name brand vs. "generic" but it makes enough difference that I won't torture my car with it to save $2 per fill up.
