But hey, it's your car.

But not for long.

Once the acetone ruins everything in the fuel system made of plastic or synthetic rubber including fuel pump diaphragm, fuel lines, connectors, fittings, seals, gaskets, and probably fuel injectors and various sensors, it will become the property of the local salvage yard because it will cost as much or more to repair it than a '94 Caddy is worth today.

This has to be the kookiest idea for improving fuel mileage I have heard so far, and there are plenty of those kook ideas floating around out there. For one thing, even if it doesn't ruin the fuel system vaporized acetone is probably more likely to explode than it is to burn when compressed and ignited in a combustion chamber, and when that happens a lot of very bad things happen to the engine's internal parts.

I should have looked at the number of comments that this thread has attracted before I posted #2097. It seems that the original topic of the thread has long since been forgotten, and that isn’t necessarily a bad thing since it was a very bad idea to begin with.

Um...I thought that in an internal combustion engine compression and ignition were supposed to result in an explosion....
