With twice the cleaning agents of our regular STP^® Gas Treatment, this super-concentrated gas treatment quickly improves the quality of gas. Powerful cleaning agents fight the accumulation of harmful carbon, gum and varnish deposits in the fuel system that can reduce performance. Also engineered to remove water, which can lead to fuel line freeze. This product is made with jet fuel, a high-quality carrier of active ingredients.

Use every other tank.

Twice as powerful as regular STP^® Gas Treatment, so recommended usage is every other tank.
