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.

Rated 5 out of 5 by Zed9655 Great Product
Ive used these product for many years and its never let me down. The trick is to use it constantly about 3-4 times a year depending on your use of the car.
Now if you have never taken care of the car, rarely an oil change or fluid changes and all of a sudden you expect miracles you will be disappointed.
This product works great but its not magical. Only Disney World is magical.

Rated 5 out of 5 by Rochoam STP Fuel Additive
I use this to keep the Fuel Injectors clean so I will not have any problems with the Engine running. I need to get all the power necessary when I am in Traffic. I do not want to have any problems when my family is in the van. I try to add a bottle of this every 4 or 5 fill ups.

Rated 3 out of 5 by CrabCake4 Easy to Use
I use this in combination with STP Octane Booster. Add this into gas when I fill up, and keep my tire pressure maintained allows my old high mileage car to get 40+ mpg on the highway.

Rated 4 out of 5 by CrabCake4 Easy to Use
I use this along with STP Gas Treatment, especially as the weather gets colder. Adding this in, along with maintaining tire pressure, keeps my old high mileage car getting 40+ mpg on the highway. Just a bit pricey; so I am not buying it all the time.
