There are almost as many stories on this subject as there are about UFOs and bigfoot.
My problem with anything that increases mileage is it has to save me money.
If the additive costs 10% more $ to run and it increases your mileage 2-5% you start running into a math problem (is it actually worth it?)

i used it before for about a year on my durango and it made a difference that was well worth the cost, acetone is pretty cheap. I ran into a slight engine problem that was pretty normal for the gen 1 4.7 liter on those durangos, but it made me wary of putting anything like that in an engine again. Was just curious if anyone else had messed around with it.
