Are there any drawbacks from the miracle cure??
I can't imagine something so cheap having such positive results w/o some kind of drawback. Things like this don't exist, do they?
Acetone is also a solvent !! So for example if you had plastic fuel lines it would eat through them very fast.
If you have one of those see through plastic in-line gasoline filters I'd be very careful. Probably should replace it with a metal one.
