Description STP® High Mileage Diesel Injector Cleaner is designed for vehicles with over 75,000 miles to remove power-robbing deposits from diesel injection systems and provide the extra protection needed. One treatment helps unclog injectors to restore accurate injector spray patterns and lost power, quickly dissolving deposits to improve the engine’s performance and restore lubrication with STP® WEARGUARD technology. The difference will, in most cases, be noticed within 50 miles. DIRECTIONS: Simply add to your fuel tank every 3000 miles.
