'Ken's Report of Directory:Acetone as a Fuel Additive Effect on Mileage and Performance'



2004 Honda Pilot AWD 3.5 v-6. Preliminary report from just miles since adding acetone reports mileage going from 20 to 25 mpg with mixture of 3 oz per 10 gallons of fuel significant increase in horsepower.

Individual Reports

I just tried acetone in my 2004 honda pilot AWD 3.5 v-6. I have only put 50 miles on it since adding the acetone but I topped off again this morning and my mixed driving mpg has gone from 20 to 25 mpg! I am mixing 3 oz per every 10 gallons of fuel. I have already noticed a significant increase in horsepower as well. It takes very little throttle to climb the same steep hills that normally takes quite a bit of pedal. I am exited about acetone and report back when I get more measured miles under my belt. Ken

2004 Pilot Fuel Mileage Update.

I have since ran two tank fulls of fuel from my first report. I am sad to say that my second fillup (at half a tank 10 gal) my fuel mileage had dropped to only 18.6 mpg. Normally my mixed driving (60 highway/40 city)ranges between 20-21 mpg.

Incidently Honda has improved city mpg with the vehicles 5 speed automatic transmission that always seems to seek 1500 rpm. Unless you drive it over 65 mph it stays at 1500 rpm and this is why I think there is actually little difference between city and hwy mpg on the pilot.

I had added 3 oz of acetone to my 10 gallons of fuel and concluded that it was to much.

When I refilled my tank I added no acetone. My next mileage reading was 23.4 (236 miles at 10.1 gallons of gasoline to fill it up to the neck!)

EPA rates the pilot at 17 city and 22 highway for comparison purposes.

My conclusion is my pilot takes very little acetone to increase the mpg. I am only going to add 1.5 oz to my next 10 gallons to see what result that gives. When I find the ideal mixture I will be sure to report it.

For now I am a believer in acetone. Even if I don't gain much in gas mileage the smell from my exhaust is the same as the air around it! That is a smell everyone can live with: zero emissions!

Greetings to all,

I have had many people contact me about my initial report and my recommendations. As such I said I would post an update so here it is:

Sorry for the long lag between reports but I have been busy with work/summer vacation/kids/dogs/home projects/ well you get the picture!

I have continously used acetone in my 2004 Honda Pilot, 2001 Chevy S-10 4.3L engine and my 93 Harley 1200 Sportser Motorcycle.

Basically the results have been simuliar.

My Chevy used to average 20 mpg with mixed driving and it now gets 23.

My motorcycle also seems to benifit from acetone. It normally gets 45-50 mpg but I have noticed it going to a solid 50 even with me getting into the throttle to hear that great Harley sound.

My Honda averages 21 mpg mixed driving and 24 on the highway.

I add approximately 2.0 ounces of acetone per 10 gallons of gasoline.

I have skipped adding acetone every other 10 gallons (half a tank on my Pilot). The reason is that I feel the acetone is accumalitive in the fuel tank. Every time you add some to the tank there is always some left in the first half of the tank. The only way I can prove this theory is to run my tank close to empty and start from nothing added into 20 gallons. I plan on doing this in the very near future. When I add acetone every 10 gallons without a break I find my mileag slipping back to stock or even worse! Has anyone else had this happen to them? If so please share your experience with us.

I will try to update this again when I have new/additional information.

Go Acetone!

Take care,



: I would recommend against emptying your tank for the following reason.

: There are floaties in fuel that tend to accumulate, and when you run the tank to empty, those floaties go through all at once and can tend to gum up the fuel filter.

: Something to bear in mind.
