'Dave Narby's Extended Test Results from Using Directory:Acetone as a Fuel Additive For Enhanced Mileage and Performance'

Cost Savings Summary

From: "dnarby" davenarby{at}gmail{dot}com


March 31, 2005

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).

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


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
