Who in the world told you to do this???
It’s a story that’s gone round the Internet a while.
THERE IS ABSOLUTELY NO WAY I’D PUT ACETONE IN MY GAS TANK.
Gasoline is already formulated by engineers who know what they are doing. Having worked in the refining industry for several decades, I am confident they know far, far more than some bozo at a local garage or some shyster with a website.
If you put acetone in your gas tank I expect one or more of the following:
1. It won’t work.
2. It won’t be economic.
3. It will hurt your engine.
4. It will impair performance.
5. It will violate the law regarding emissions.
The most important thing is not to buy more octane than your engine needs. If the owner’s manual says Regular (87 Octane in most areas), don’t waste your money on Premium. Personally, I’ve had good experience with topping off with Regular even with cars that called for Premium, but I had to pay attention to engine knock. If the engine doesn’t knock, it does not need higher octane and you’re just wasting money. The ONLY thing octane does is to prevent engine knock.
