I f you go out to your garage, or any automotive parts store, and pick up a can of carb cleaner you'll find that the main ingredient is acetone

Just a quick update. Tank #3 with acetone 14mpg exactly. I am going to run no acetone in the next tank to see what the change is.

Funny... I use just about any grade of fuel. What ever is cheaper! If I'm running the cheapest shit then I usually through in some injector cleaner and I've NEVER had issues with knocking. Maybe I'm just lucky.

Of course I'm unlucky in other respects, as every damn D90 project that I work on I seem to break bolts off left and right.

Acetone Experiment

I have an ongoing Acetone experiment on our Mazda that's been going on now for a couple of months. Results can be found here, you might find of some interest:

Michael are you adding 4-5 ounces per tank of fuel or per gallon of fuel? In your tank results it looks like you are adding 4-5 ounces each time you fill up, which would be more along the lines of what was said earlier in this thread. But on this page http://www.pigmtnfarm.com/mnoe/acetone_faq.html you say to use 4-5 oz per gallon of fuel.

Yeah, my bad, thanks for the catch.

It's 4-5oz per 10 gallons of fuel. I'm doing about 4-5oz per tank on the Mazda.

Just an update for anyone who is still following this. My mpg in the 130 for the last tank was 10.5mpg with acetone. The previous tank without acetone was 7.5mpg. Not a bad gain. 10.5mpg still sucks but is way better than 7.5.

That's a good gain, thanks for staying on it for us. I have to admit, however, everytime I see a new post to this part of me thinks it's going to say, "Fuel lines ruptured, but it was a nice carbecue."

Acetone

So I am watching Mythbusters last night and they are doing a bit on fuel saving devices, they did the magnet on the fuel line and a bunch of other snake oil fixes. They also did the acetone test. Well I have been using acetone for the last year off and on and have seen at the least something like 2mpg increase with actone and the best tank was a 4mpg increase. I use 4oz in 20 gal of gas. I dont know what the Mythbusters used but they used a 1 gal. of gas for the test and it looked like they put in at least a few ounces of acetone into the 1 gal. of gas, way too much acetone. Anyway there test showed a decrease of 1mpg with acetone and theyy called in busted.

Maybe when I use the acetone I drive with a lighter foot but I cant deny the fact that I get more mpg when using acetone. 2mpg is alot when you are talking about a truck that normaly gets 8mpg.
I think I will keep using it. BTW I have been putting acetone in my wifes 1994 Disco without her knowing it and the results are the same, 2-4mpg increase. If you use more than 4-5oz in 20 gal. fuel economy drops.

I use 100% . I bought a few nail polish remover bottles that are 6oz bottles and use those to store the 100% acetone that I buy from Home Depot in a 1 gal. can.

I've been using it for almost a year now, in the following vehicles:
'99D2
'93Mazda Protege
'96Massey Ferguson MF362 (Perkins 4-cyl Diesel, normally aspirated, only 3 tanks so far)
'98Polaris Sportsman 500

I use the ratio of about 3-5oz per 10gal of gasoline, about 2oz per 10gal of diesel. I have noticed a definite improvement in all of these vehicles' mpg and general running condition. I think that MythBusters test is bunk.

I use the 100% stuff you get at the hardware store.

I've tested it a lot over the last year on and off. Without fail, MPG improves with acetone. I record the fuel flow rates on a Carchip EX and absolutely without a doubt see improvements from 2mpg to as much as 5.5mpg on long trips. I made a trip from VT to VA without, then in similar weather and traffic conditions drove back to VT w/acetone- 5.5mpg better. Hope it's not wrecking my rubber or plastic parts in my fuel system.

I think this might be good to merge with the other Acetone thread we had going a little while ago and move it to the Tech section. Pretty interesting I think.

I think we have to keep in mind how fast acetone evaporates. Pore some on a non porous surface and watch it. Now in a fuel system that is sealed (not vented ) and being driven on a long trip immediately, good chance all of it will be make it to the combustion chamber. But if 5 oz were added to a tank that has a breather and charcoal tank and driven on and off for 2 weeks before refill I'm not sure how much of that 5 osz would actually get combusted, before it evaporates.
