Acetone in gas tank

Yep, toluene is an additive we use...

3-nitro-toluol in a gas tank?

I don't want to be anywhere near it.

if you put 15 gallons of acetone and one gallon of gas in your 16 gallon tank, you'll go 300 miles on a gallon of gas!

(if the hoses don't melt first.... and the acetone actually ignites...)

in my experience, it seems to stay at a 10-15c price difference regardless of the actual cost. with high gas prices now, it's a negligible difference for me. thankfully so, since my high compression engine requires 91 :/

I can assume that there may be some truth in reports of a mileage increase, but the same increase may be gained by spending 1-2 tanks of a premium gasoline, in order to clean injectors, if they got so dirty so need some cleaning. At least, gasoline is less aggressive on plastics than acetone.

1-2 tanks of premium will not clean injectors. "Premium" only means an increased octane number. Also, those "injector cleaners in a bottle" won't do much good either.

The only thing that actually cleans your injectors is taking them out, and putting them on an ultrasonic injector cleaner.

Yeah I have a 2002 Acura RSX Type S with the 2 liter 4 banger, it's static compression ratio is 11:1 .. makes 1HP per 10cc of displacement. ) Requires 91 octane minimum and runs noticeably better on 93 octane. Car is surprisingly durable, although I no longer beat on it much, (Honda S2000 manages 240HP with a modestly basically tweaked version of this engine. One of my neighbors had a very built RSX with a centrifugal blower and that engine made about 380HP, about 70% more torque than stock, despite driving it like a maniac he neither blew it up or crashed it. Sadly traded for a Nissan 350Z which IMO is way more refined, but less cool.)

Are you sure?
I thought it is really refined better, that's why is more expensive.

97 prelude, 2.2liter. after 12 years and dozens of trips to 7400 rpm, still runs like new. better mileage actually it's rated 22/27, but i've been getting over 30mpg on several recent trips. I wonder what went in the tank...

of course the honda ignition switch bug is hitting me. In classic diy style, I'm contemplating putting in a separate power switch and start button instead of replacing it (... and for all you ppl on the internet trying to find me thinking it will be easier to steal... it won't )

yes, it's ot, but this is 'Everything Else' isn't it? all's fair here and i just spent 3 hours chilling to music so i'm happy

I promise. The two grades are made from the same refined base, and then different additive packages are added to create either high or low octane gas. You are paying for more expensive octane additives. There are only 2 separate grades of gas, 87 and 91/93 -- mid-grade gas is a mixture of a certain ratio of them to achieve 89.

Honestly, it depends more on the company than the octane number when it comes to detergent effects, as different companies use different additive packages. But even those differences are pretty small. It's less about cleaning and more about preventing carbon build-up by producing a pure and complete-burning product.

Basically, if your engine was designed to use 87, use 87. If it was designed for 91/93, use 91/93. Buy gas from a company with a good repuation; Shell (v-power) and Chevron (techron) come to mind. If you would like to clean your injectors, get them cleaned. It only costs about $30-50.
