Doc’s Diesel Clean & Protect Bundle

Doc’s Diesel Clean & Protect Bundle: Modern diesel engines deliver serious power, but they demand serious protection. Injector deposits, soot buildup, and internal friction slowly rob performance and lead to expensive repairs. This bundle was built to clean and protect your diesel the right way, combining targeted fuel system cleaning with critical engine wear protection. Interval Diesel Treatment delivers a concentrated clean to help restore injector spray pattern, improve combustion performance, and reduce deposit buildup that can impact efficiency and power. Oil Friction Treatment protects where wear matters most — inside the engine — reducing metal-on-metal contact and helping safeguard components under heavy load, towing, and high-heat conditions. From combustion efficiency to internal engine protection, this bundle helps defend performance where diesel engines need it most. Product Details: View each item for individual product specs.
