What if you could actually improve your gas mileage significantly (5-20%), without having to alter your driving habits? Without installing any extra questionable parts on your car? What if it were as easy to do as 1-2-3?

Well, it is.

For years, Big Oil has offered three different grades of gas octane: 95 special, and 98 premium (Super). These grades are actually based upon a 100-octane scale, in which the cleanest-burning, most ideal fuel was propane (clean burn fuel). But the scale doesn’t account for aromatic petrol compounds and derivatives, which can actually surpass the 100-octane mark, some as high as 115-130 octane.

So, our objective is to get the engine running the cleanest-burning fuel possible, leave the smallest amount of soot and deposits in the combustion chamber and on the valves, clean the injection system (or, in older cars, the carburetor), not hurt emissions systems, not void our warranty, and, in the end, get increased gas mileage and increased engine life. Wow, that’s a lot! It really isn’t, though.

Recent tests have proven that aromatic petroleum distillates such as alcohol (methyl alcohol), ether, acetone, and toluene can and will do all of these – to a point, that is. If you make the fuel mixture too rich, you can actually do the opposite. According to the research, the ideal mixture that was also easiest to obtain and handle was 1-2 ounces of acetone per full tank. Acetone can be found at your local hardware store or paint supply shop. It was tested on everything from 4-8 cylinder gas engines to big Cummings diesel engines. The range in increase of fuel efficiency was 5-20%, the average being 9%.

Three ounces per full tank, however, resulted in the same fuel efficiency that zero ounces did: three is too much.

The effects of the acetone were then tested on the fuel line components themselves for resilience, and it was found that unlike methyl alcohol (racing fuel), it did not have a caustic effect. Acetone does, however, have an etching effect on paint, plastic headlight lenses, etc. Spills should be cleaned up immediately.

So, to make the story short and get straight to the point, if you want to add an average of 9% fuel efficiency to your vehicle cheaply, its as easy as adding 1-2 ounces of acetone per tank fill. That’s it. Why haven’t you heard about this before? The problem is that Big Oil companies don’t want you to know how to save on gas, and so in some cases, you may still void your warranty, as they now test for gas additives like acetone.

Also, one last note: acetone or any additive that makes your engine more efficient also makes it burn cleaner: fewer emissions are better for the environment, so drive more efficiently today.
