We run a ratio of 1:320 acetone to gasoline (4 oz per 10 gal). This
creates a 10% increase in MPG (conservatively) which translates to a
10% savings in fuel.
Therefore, for every gallon of acetone you run through your car, you save 32 gallons of fuel (10% of 320 gallons).
1 gallon of acetone costs about $10.00 32 Gallons of fuel costs about $64.00
Therefore, for every gallon of acetone used, you save $54.00 (as of this writing).
Best,
Dave

Hey all,
FYI I've been running acetone in two vehicles (Dodge caravan V6, Merc Sable V6) for about 9 months or so. I've noticed a few things in the process.
Lou recommends 4 oz per 10 gallons. This amount seems to work good for most people, and it did for me. Some people seem to get better results running a little LESS acetone, perhaps 2-3 oz. For myself, in order to avoid overdosing, I reduce the dosage of acetone to 2 ounces per 10 gallons on every third or fourth fill-up." Running MORE acetone DEGRADES fuel economy, so DO NOT USE TOO MUCH. More is not better! Listen to Lou! He is right!
Typically I will only add 2 ounces per 10 gallons every third fill up to help avoid overdosing. This is the only point where I differ from Lou, he reccomends skipping every third tankful or so. I'm lucky that I have a surprisingly accurate fuel gauge so I can easily estimate how much gas I'm going to need, so I can get away doing this IMO.
I buy it in gallon cans at Auto Zone and measure it out in a graduated long neck plastic bottle used to spray insecticide I found lying around (you can probably get one like it in the garden department of your local non-Wal-mart). I also bought a funnel to fill the bottle with.
I also noticed that acetone works a bit less in the winter. The MTBE (or whatever) they add to the fuel to reduce emissions REALLY screws up your fuel economy (in my case, 20%). Talk about a boondoggle... Reduce emissions by 15%, but increase consumption by 20%... Net gain in emissions to the envrionment = 5%. Your tax dollars at work.
I've also soaked fuel delivery components in 100% acetone (gaskets, lines, fittings etc.). I even sawed a fuel injector in half to get at the bits on the inside.
What I found is that some gasket material will swell in straight acetone. Fuel lines and fittings do not react - period. To determine what would happen running 1:320 acetone:gasoline, I soaked these suspect parts in this mix (I actually used a double strength mix to be on the safe side - 1:160). The gaskets swelled very, very slightly, just enough to be noticable if you have good eyes. My wife didn't see it.
My final analysis is that acetone gives 90% of people out there an MPG boost, and if you have a leaky fuel system, it may swell your gaskets slightly and seal the leaks.
Best regards all and good luck,
Dave Narby
