Acetone? Has anyone actually had any damage from using acetone?

The whole point of octane is resistance to burning.. so that it ignites via spark no compression and heat.

If anything from this "research" i would think the acetone has a greater benefit of diluting the ethanol in the gas than making the gas better.

I see the logic behind that, and that's what I assumed at first until I researched the effect of acetone on gasoline. I also figured that given such small amounts being used, the only way it make a real difference is at the molecular level. I'm not going to pretend to understand all of the chemistry behind it. But the information repeatedly given on this was stating that it reduced the surface tension of the gasoline by changing the molecular structure (essentially from a block shape to a more efficiently burning popcorn type shape) resulting in reduced surface tension. I can't vouch for the results at this point as I've only been using it a short time and haven't. Logged mileage since starting to use it at the recommended amounts. I can tell you that after starting using militec-1 in my oil for a few thousand miles, having regular oil changes, using mmo every other fillup (this also helps to offset any drying effect the small amount of acetone may cause) and using 2-3 oz of acetone with each fillup, my cars acceleration is much smoother. Its much more noticeable in 5th gear. It takes higher speeds before I feel the engine straining. Once I get some miles logged with these additives, I intend on switching to copper spark plugs as well for improved performance (although soomewhat minor).
