I understood completely what you were saying, but you were stating that our cars would be fine running 85, this I do not agree with. Thats all I was saying. Plus you never did reference where in the manual it states that timing will be retarted if you use low octane fuel.

Agreed...also, I would say a SC or Turbo kit running higher boost would see the benefits of race gas. Putting it an stock engine is a waste of money. In addition, you'll end up fouling out your O2 sensors faster.

The 91 is fine, the car will adjust timing if need be. Running race gas isn't getting you much if any power at all.

Well its cool of everyone to give their points of view. Like I said I was just trying it out, and I was surprisingly impressed. Most likely, I will prob just pump 91 merely for the fact that its cheaper.

I think you should just run race gas from here on out.

Get in my car, drive away and my gas measurement didn't go all the way up. The last light didn't light up. Weird, but anyway I gotta say, I can really tell the difference in Race Gas. Not like a performance boost, but just snappier and the throttle seemed a lot more responsive. Love it! Between the $100 oil changes and the $100 gas fill-ups, I'm gonna have to get a second job

Every now and then ….why not. How much per gallon? My 101 octane source is about 30 miles away and $8.45 per gallon.

$8.99/gallon for 100 octane. Kinda expensive, but its Newport Beach, + its the closest to me.

psh toluene people i think i'm heading over to sherwin william's tomorrow to pick up a 5 gallon pal for $35 bucks. at one gallon to every 19 of 93 thats 100gallons of race gas $335 bucks. beat that.

HAHA 3.34 a gallon for 110 race gas FTMFW!

^ Any residue left? I mean...why doesn't everyone do this..there must be a reason.

your crazy but i like where your heads at

toluene is added to gasolines (especially race fuel) from the refinery, It was first phased out by MMT which does the same thing but is a waste product of plastic production so it's dirt cheap for the refineries as they would just dispose of it otherwise. Then the EPA being the way it is and MMT making ground water under a spill zone taste like crap, ethanol has been getting phased in as the new octane enhancer/oxigenator, even though it costs significantly more. Government subsidies have been put in place to make the ethanol affordable for the gas companies. My guess is most people don't know about toluene (also called toluol at the sherwin williams) or that it can be purchased locally for next to nothing. I went into the sherwin williams asked for toluene and he said "we only carry un-recycled automotive grade so it will cost more" $35 dollars later i walked out with 5 gallons which is enough to treat 95 gallons of 93 octane fuel and achieve 110 octane. I wish i could get my hands on some propylene oxide but the EPA began regulating it as it is known to the state of california to cause cancer

what isn't? also if you spill propylene oxide on yourself you better get rinsing as it is a skin absorbed poison.

Why is anyone running race gas? You must have massive engine mods to require higher octane (to avoide spark retard which prevents knock)...

Higher octane fuel provides NO benefit to a stock engine. Octane only increases the knock limit of an engine, and our engines are designed for 92 octane.

psychological effect. Octane is a chemical added which makes the fuel harder to burn. This prevents pre-combustion, or knock, which can help engines that are either old and have carbon build up which causes hot spots, or modified high comression engines (pressure+temperature causes ignition), or engines that run extremely hot due to very high power output. Your brand new stock engine will not knock on premium fuel, unless it's 140F outside, therefore your engine will not advance the spark, which will not reduce the power output. Fact. Ask an engine engineer. Oh yeah, I am one. That's your answer.
