I used to use Gumout or whatever until my brother got me started on Techron. It worked pretty well, and I know it's popular.
Recently a 125K mile car of mine was idling rough.. I tried a bottle of techron.. it helped some... next month, problem's back. Thought I'd try something else.
Got some Justice Bros. Made the mistake of smelling it... that will KILL YOU! Poured it in. Actually got an extra 25 miles out of that tank, and it's run better since... with just straight gasoline. The improved mileage continues. JB's is the most succesful I've had.
