Marathon Gasoline

Marathon gasoline is certified Top Tier™, providing a higher level of STP^® detergent additive for even greater cleaning power. Marathon gasoline fights the accumulation of harmful deposits and improves the performance of your vehicle's engine.

Optimizes Fuel Economy.

Deposits in engines can reduce fuel economy. Compared to gasoline using only the minimum Environmental Protection Agency (EPA) required the dose of detergent additives, Marathon gasoline with STP^® additives can increase fuel efficiency by improving the cleanliness of an engine’s intake valves.

Removes deposit buildup.

Marathon gasoline with STP^® additives provides deposit control detergents that remove the buildup of performance-robbing deposits. Marathon gasoline is specifically formulated to help maintain engine cleanliness, therefore, improve engine quality.

Reduces emissions.

By keeping intake valves clean, engines have fewer deposits, which can lower harmful emissions like nitrogen oxides, hydrocarbons, and carbon monoxide in the engine exhaust. Marathon gasoline with STP^® additives clean engine intake valves and reduce emissions.

Restores lost power.

Marathon gasoline with STP^® additives can remove deposits in your engine’s intake valves. Lower quality gasoline has the potential to leave more deposits, which will have a negative impact on your vehicle’s performance. A cleaner engine will keep your vehicle running its best.
