Rated 4 out of 5 by from 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 from 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 from 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 from 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 from 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.
