Gumout Octane Booster is my choice for any factory muscle car, and my every day drivers.
on January 27, 2014
Gumout Octane Booster is the only product that keeps my Custom 2001 Toyota Tundra running at peak performance. Adds more mileage to every tank and will never allow my motor to sputter or knock. This is not a fuel additive designed for super high horsepower engines. But works great for anyone, with a few extra horses under the hood. Trust me, I have tried them all, and this also works well in the tanks of my classic, new and modified muscle car collection.
