Microlon Products has a special formulation just for the heavy duty requirements of diesel engines. Most diesel engines are under tremendous loads, this requires extra protection from the damaging effects of friction. The increased torque and potential fuel savings are the primary reasons the Microlon Diesel formulation is so highly regarded by commercial truck operators who use it. Experience also tells us that treated diesel engines require maintenance less frequently and have a longer service life. To those who make their living with their diesel rigs, it means lower operating costs and higher profits.
