Doc’s Diesel Long-Haul Protection Kit

Doc’s Diesel Long-Haul Protection Kit:

Modern diesel engines are built for the long haul, but constant load, heat, and friction take a toll over time. Low-lubricity fuel and internal engine wear slowly reduce efficiency, performance, and long-term durability. This kit was designed for diesel owners who plan to keep their truck for the long run, delivering consistent fuel system protection and internal engine defense with every mile.

24/7 Diesel Treatment goes in every tank to support fuel lubricity, maintain injector cleanliness, and help keep your fuel system operating efficiently day in and day out.

Oil Friction Treatment protects where durability matters most — inside the engine — reducing metal-on-metal contact and helping safeguard critical components under heavy load, towing, and high-heat conditions.

From the fuel tank to the crankcase, this kit helps support smoother operation, improved efficiency, and long-term engine reliability, mile after mile.
