Hi all,

I read the post on using Acetone as a fuel additive from a couple months ago. I thought it was interesting, and I may try it on my queen of the klunker collection sometime. Since its been some time since the thread was started, I'd like to get more information, opinions and such. From others observations from using the stuff.

Thanks,
Alvie.

 

I seriously doubt it does much if anytthing at all... I think you'd get better results from propane, methanol, water, or NOX injection.

 

acetone is a great fuel additive and will help any gasser get better performance, and clean injectors and valves in the engine but you need to be carefull cause you can also damadge the engine or if it is a high mileage one it can cause leaks in the valves and rings. acetone is the main ingredient in the octaine boosters and fuel injector cleaners. i would stay away from methanol on later model engines. but if it is for racing application acetone isnt that great you would have better luck with NOX-injection

 

I'd be careful with the acetone. Wouldn't it tend to damage the coating in the intake manifold? (Don't know for sure, just asking)

I was told for instance that I should use "intake manifold" cleaner/spray and not old generic carb cleaner for my intakes, as the manifold has some sort of coating. (93 f150 5.0)

 

I don't think you should use it if you have a plastic manifold. Other than that, its an excellent cleaner and very high octane, so it burns cooler than gasoline.

 

so how much would you add for every gallon to make the most out of it?

 

Would you run B-12 Chemtool in your gas? It's 80% acetone. If you want to run acetone for a cleaner, use 4 oz per 10 gallons of fuel. If you want it for the performance gains, run 2 oz per 10 gallons of fuel. It works by reducing surface tension of the fuel which enhances the the vaporization. It is also 150 octane so expect to see some performance gains. If you have a late model engine, it shouldn't hurt it to run it all of the time. Earlier fuel systems may not like it. Do not get it on the paint as it works well as a paint remover. Avoid contact with most plastics. I use it as a cleaner ever 3,000 miles and add 6 oz to my 04 Screws tank. I use a funnel with spout to get it into the tank. It vaoporizes quicker than alcohol so don't let it stand open to the air.

 

I was going to post that but you beat me to it.

 

Hi all,

Thanks for replying to my post. Its been quite informative. I was only interested in using acetone as a fuel additive to increase gas milage. I don't have any interest in using it to increase performance. If I was racing cars, yeah sure, but others have pointed out better ways to do that.

What is the stuff that makes up STP and cheap fuel injector cleaners? I know they say to stay away from it, I think its ethanol alchohol. They say the stuff can actually do more damage then good.

 

It kinda sounds like it could be used as a octane booster, from what Flash posted. I wonder if this would be a cheaper way to boost octane for those of use that have tuners and chips, rather than buying premium fuel, or when the high octane stuff is not available.

I wonder what amount it would take to bump up a 25 gal tank from 87 to 93 octane.

Flash, when you say acetone is 150 octane, is that per ounce or per gallon? When I run my simple average formula that I reasoned out (using 150 octane per gallon), I come up with 2.6 gallons of acetone needed to bump 25 gallons from 87 to 93 octane.

Here's what I came up with for a formula.

((25 gallons of gas)(87 octane per gallon of gas) + (Y gallons of acetone)(150 octane per gallon of acetone))/(25 + Y) = 93

Any thoughts? Or is my understanding of octane all screwed up?

 

Acetone is extremely volatile. Use it only as a fuel system cleaner. The article I read said it was safe up to a ten percent mixture, but I would never run that.
