A test: Acetone in gasoline, better MPG?

I've been reading up on this for quite a while, and I am ready to start testing it in my Vulcan to see if it can make any difference in performance and mileage.

I've been keeping track of my mileage over the last two months. I haven't been on any trips, just my daily riding to and from work, around town etc. and I've been getting a consistant 46 mpg for quite some time.

I'll start by adding the smallest amount of acetone to a full tank of gas. My first test will be to add 1/4 oz to a full tank. That's just a sip. I'll let you know what it does to my performance and mpg... Stay tuned.

Yea, it's a little known item. But, it's better to run acetone than to run milk. At 3/4 oz of milk, my bike started having trouble. Next I'll try squirrel.

I tried chipmonk, but the hairs got in the carb and ewww...

No really, I have never heard of acetone as a gas additive... can you give us some background on the logic behind it?

Acetone is highly flamable just be careful it can melt some plastics.You could probably try using lacqer thinner also thats also highly combustable.........

OK, guys, do a search in these here forums on 'acetone'. This topic has been covered once already. Acetone in gasoline isn't straight acetone, which eats plastic. Just like the fact that I poured pure hydrochloric acid on my shirt yesterday. It didn't burn me because it was diluted in alcohol. (97% to be exact).

Depends on the dilution, and time. You can drop a dead mouse in Coke, and it will be a wet dead mouse. But if you leave it there for a long time, the acid in the Coke will eat away at the mouse, and the mouse will be no more. At least that's what they say.

As to not burning clean, who cares?

If you folks want to read some of the information on this, go here: http://www.pureenergysystems.com/new...00069_Acetone/

The basis for adding acetone to gas is this: Gasoline has pretty high surface tension, which causes it not to vaporize very effectively. Carbs and fuel injection systems bring gas mixed with air into the combustion chamber as a vapor. Because of the surface tension, there are droplets of gas that get in there and go unburned, causing the system to be less effecient. Acetone has very good vaporization capability and when added to gasoline in tiny amounts, it can greatly improve the vaporization of gasoline, making it burn more completely, using less gas to generate the energy needed to move the vehicle, less waste, and less emissions--all good. That's the idea. Hopefully my testing will show something, whether good or bad. These guys have been testing this for many years using techniques much more advanced than I can do with my daily riding. Plus, you are supposed to test different gasolines in your vehicle to try to find a brand that works best "before" you start testing with acetone. Kind of hard to do on a bike, especially if you have to do any long distance riding...

My first tank of gas was pretty used up yesterday when I made a trip to Austin after work, bucking a North wind that was pretty strong, hitting me mostly from the side, and averaging 70 mph. I got 43 mpg on the two gallons I used before I filled up to head back last night. The wind conditions and 70 mpg probably had something to do with the lower mileage. I added acetone back to the full tank in proportion to make the same gas/acetone ratio and will continue to monitor the mileage. I'll be mostly riding in my normal around rural roads style for a while so I assume it will improve with my slower riding. We'll see.

(I added just less than 1/8 oz back to the full tank trying to get close to my 1/4 oz per tank of gas for my testing)
