Well, I got a 20% repeatable A-B-A-B-A etc. gain with Acetone.
41+ with acetone
35 without acetone
Same route, both ways, same driving, etc. Now I guess the best thing to do would be have someone applying the additive (or not) for me, and see if it was the placebo effect or the Acetone
It made a kick-@$$ injector cleaner, however!
