Deep Cleaning Diesel Fuel Injector Treatment

Over time, diesel fuel injectors can accumulate internal and external deposits that affect fuel spray patterns, injector operation, and combustion quality. Hot Shot's Secret Diesel Extreme Injector Cleaner uses concentrated cleaning detergents to help remove these deposits and maintain a cleaner fuel system.

Removing deposits can help support smoother engine operation, consistent fuel delivery, improved throttle response, and reliable diesel engine performance.

Diesel Cetane Booster & Fuel System Protection

Diesel Extreme includes a powerful cetane improver capable of increasing diesel fuel cetane ratings by up to 7 points, depending on fuel quality and treatment conditions. Improved cetane can support smoother ignition, better combustion, and improved cold-start performance.

The formula also contains lubricity additives, corrosion inhibitors, fuel stabilizers, and moisture-control ingredients to help protect fuel pumps, injectors, and other critical diesel fuel system components.
