1991 Pontiac Bonneville Q&A
1991 Pontiac Bonneville Question: Do fuel injector cleaners work?
Some do, some do not. At the shop I used to work at, and in all of my personal vehicles, we used B&G 44K it is kind of hard to find, and is very expensive ($30+ a can) compared to others out there, but we have always had good luck with it. However, it is very agressive and strong, so we always told folks to put it in at the gas station before you fuel up. Top off the tank, and only drive it down to 1/2 a tank, then refuel completely. - Wilsonite
