BG 245 Premium Diesel Fuel System Cleaner effectively removes deposits from the entire diesel injection system, including fuel injectors and combustion chambers. Diesel fuel instability can lead to buildup, causing power loss and increased emissions. In high-pressure common rail (HPCR) engines, extreme temperatures accelerate carbon deposit formation, reducing efficiency. Unlike typical cleaners that only target injector tips, BG 245 cleans the entire system, including inside injectors. It also improves fuel lubricity and contains a cetane booster for better cold starts and performance. ⚠ Warning: Contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
