Rated 5 out of 5 by RamblinMan Very reliable additive!
I always go to Pep Boys for my gasoline additives! They always have them and the price is reasonable!
I would recommend the additive and Pep Boys to anyone.

Rated 4 out of 5 by JC52 STPgas treatment boosts gas octane
I love STP gas additive because I am able to fill my tank with 'Regular'-unleaded and gas prices are at their lowest ever since before 2005.
