Thanks. I should have some info by the end of the week, and I'm planning to give this experiment some time.

Just got 35 mpg from my last tank. I increased my acetone input to 4 oz for the latest fill up, and am running 1 oz each of the GP7/toulene/xylene/mpz.

I just started reading this thread and I have a 1990 buick reatta with the 3.8 engine and can get close to 30mpg without acetone. On a trip to Nashville one time I computed the mileage without the long traffic jam (it has a built in code reader) and came up with close to 35mpg. Personally I think that most of the mileage gains/losses are from tuning and some are from driving habits.
