Efficiency starts with good maintenance, and keeping everything working the way it was supposed to.Dirty injectors can hurt spray pattern, combustion and performance. Poor lubricity adds wear to pumps and injectors. Old oil has spent its life carrying heat and contamination around the engine, and loses it's best lubrication ability quicker than we all think.

Our Hot Shot’s Secret lineup gives you a simple routine: quality synthetic oil and the right filter at service time, EDT in every tank, and Diesel Extreme about every 6,000 miles for a deeper fuel-system cleaning. Boring maintenance. Expensive problems avoided. You'll notice the difference.

EDT - Every tank maintenance to help keep the fuel system clean and lubricated.
