Deep Cleaning Diesel Fuel Injector Treatment

Diesel fuel injectors can develop internal and external deposits that interfere with fuel delivery and spray patterns. Hot Shot's Secret Diesel Extreme Injector Cleaner uses concentrated detergents to help remove these deposits and maintain proper fuel injector operation.

Regular deep-cleaning maintenance can help support consistent engine performance and reduce fuel-system problems associated with deposit buildup.

Diesel Cetane Booster & Fuel System Protection

Diesel Extreme contains a cetane improver that can increase diesel fuel cetane ratings by up to 7 points, depending on fuel quality and treatment conditions. Improved ignition quality can help support smoother engine operation, cold starting, and efficient combustion.

The formula also includes lubricity enhancers, corrosion inhibitors, moisture-control additives, and fuel stabilizers to help protect fuel pumps, injectors, and other fuel system components.
