Pure acetone was rated in 1920 by Sir Harry Ricardo at 150 octane. Plus acetone turned out to be an excellent additive to reduce exhaust emissions in both gas and diesel engines.
Octane booster... But in such small quantities, probably unnoticable.

Now a warning.

Let'* assume you run 1% of an additive with 99% fuel. You run your tank down to 1/4, and add/fill again at the 1% mix. You actually have more than 1% now. And each successive tank gets stronger.

This is even more dangerous on the additives that you can't exceed a low threshold on. Now imagine adding one or two GALLONS of Toluene like I do sometimes. I have to track my octane in a spreadsheet, so I know what the previous tank was, use that as my starting point, and re-mix. I have to know before I go to the gas station what I intend to put in the tank.

Don't blow your car up. I live by my spreadsheet.

Yeah, I see what you're saying. Without keeping track you'd be "stacking" more and more acetone in your tank over time. I might set up an Excel spreadsheet to try this stuff. If acetone is an octane booster like MyLittleBlackBird says, I shouldn't have any KR problems. Thoughts, opinions, criticisms?

If you're interested in octane boosting, forget Acetone. Toluene is what everyone uses for a reason. It'* a natural element in gasoline already, and has been proven time and time again, including in 3 SSEi'* here that I know of.

I'm not interested in acetone as an octane booster, but rather for the gas mileage purposes that were suggested. I'm concerned about what it does to my octane level because of the advanced timing I run with my PCM. I know a few ounces in a full tank of gas shouldn't do much to the octane, but I'd still like to know of any potential effects it could have. I'm very interested in improving mileage for obvious reasons (can anybody say $2 gas?), so I think this theory is worth a shot. If you can give me any pointers on how to set up my Excel spreadsheet I'd appreciate it.

By the way, Will, check your PMs. I haven't heard back from you lately.

So the toulene raises octane rating? And Acetone improves mileage and cleans???? Am I understanding this correctly? I'm assuming that the toulene is catalytic safe??

Could you get 87 octane and ad toulene to bring the rating up to 91+ OCT?

Where ya been, Lakeville? Do a search for "toluene" and you'll see how much this has been discussed. Tested by many here and proven to be effective.

It'* not cost-effective to raise octane on a daily basis with Toluene. The stuff is 6-8 bucks a gallon, and I put two gallons in sometimes. It'* cheaper to BUY 91.

I buy 92 and mix up from there for the track or mountainous trips in the heat.
