I don't know where I heard it first, but I've recently been putting a little acetone in my fuel tanks to help with economy. It seems to work.

What I've heard is that the acetone helps with fuel vaporization. But I also think it's been cleaning the injectors. My wife's Jeep with the 5.2l V8 has been running much smoother since I've run three tanks of gas with a little acetone. Fuel economy has picked up from about 15.5 to 17 or more in town, and from 21 to 23 mph on the highway.

I'm leery of using it for stop-and-go driving. I supect that it's hard on rubber and plastic, and it might overload the vapor canister system because of the increased vaporization of fuel. But if you're going to be taking a trip and burning though a few tanks of gas, I recommend getting a gallon of acetone, and adding about 4 ounces per 10 gallons of gas.

 

anyone ever hear of anything like this before? is this kinda like adding fuel cleaner?

 

Any of the solvents in the Keytone family will be a plasticizer meaning that it can destroy/dissolve plastics. It is a 150 octane rated fluid and is hot meaning that it vaporizes rapidly. There is no real science behind it to say that it works. B-12 Chemtool uses it a a carrier fluid. I would excerise caution in putting it in your tank as it also is a great paint remover.

 

If a gallon of gas is 128 ounces, 10 gallon is 1280 ounces, and you're adding 4 ounces of acetone, that's about .3%; 3/10ths of one percent. What I hear is that it lowers the pressure of vaporization. The fuel vaporizes at a lower temperature.

In a closed-loop electronic fuel injection system, better vaporization means 'leaner' mixtures. I quote the word 'leaner' because the oxygen sensor will adjust the mixture to deliver less fuel, but that's because less fuel goes out the tailpipe. The air/fuel mixture is lower because it takes less fuel to use up all the oxygen in the combustion chamber. Less carbon on the valves, less on the piston tops, cooler running cats.

I've also heard that the main ingredient in fuel additives is acetone. I think that at 3/10ths of 1% level, it's worth doing, especially on trips.

 

hmmmm so adding b-12 chemtool is pretty much the same thing? or no? just wondering cause i take long trips pretty regular.... usually around 1400 miles one way - so even a couple extra miles per gallon will make a noticable difference.

 

It also affects brain cells and can make you go bug-eyed!

 

so no more sniffing to check for "purity"?

 

Well, the MSDS says that Berryman B-12 Chemtool Summer Diesel Treatment is 85% kerosene(CAS 8008-20-6), and 15% other. Short answer, you'll have to do your own research to find that out.

 

well on another board im on (for explorers) they say to mix 1 oz per 10 gallons one guy who has his explorer up to 30 mpg tried this and found out it up his milage by 1.5 mile per gallon..you have to play with the amount for your vehicle and they also said it takes up to 3 tanks for it to take affects..

 

i have just done some research on this myself and i have decided not to go ahead with this. Acetone can eat away fuel lines after a while. you might be saving your self right now but what happens when you have to get a new fuel line because the acetone ate it...?

 

Everybody has to make up their own mind, but I've been using it for a while with no ill effects. I have seen it dissolve polycarbonate (clear plastic) measuring cups, but I not aware of problems with polychloroprene (neoprene aka fuel lines).

 

at one or two ounces per 10 gallons, is there even enough there to worry about doing damage to the seals?

 

acetone can also do damage to engine pistons. so use this at your own risk

 

Oh, come on! I call bullcrap. Tell me how that happens. What's next, it eats cast iron?

Look up acetone in Wikipedia and you'll see that it's a naturally occurring substance. Your body makes it.

 

keep throwing the junk into your truck and get back to me. im actually thinking about purchasing a diesel VW and going with bio diesel
