STP® Fuel Additives Fight Deposits

The problem with most car engines:

Impurities in gasoline can cause deposits to form in fuel injectors, intake valves and combustion chambers. This is an issue in both old and new engines. Harmful deposits can form in less that 3,000 miles and cause:

• Lower gas mileage
• Poor acceleration and lost power
• Hard starts
• Auto ignition (knock and ping)
• Increased exhaust emissions

The Solution:

STP Complete Fuel System Cleaner — our strongest formula — contains powerful detergents to help remove harmful deposits. One tank treatment helps clean the entire fuel system — fuel injectors, intake valves, even hard-to-reach combustion chambers — to help optimize engine performance.
