Add TRUCK ENGINE TREATMENT to your clean oil during an oil change to make the engine start easier, run cooler, produce more horsepower, and improve gas mileage.
Large diesel trucks are expensive to run and costly to repair. One of the money-saving benefits of using TRUCK ENGINE TREATMENT is fewer repair bills. Our TRUCK ENGINE TREATMENT is based on the Tufoil technology, which is considered "The World's Most Efficient Lubricant" by the Guinness Book of World Records.
Engines that run efficiently need fewer repairs, use less gas and ultimately last a whole lot longer.
Tufoil TRUCK ENGINE TREATMENT is specially packaged in a handy 1.5 liter size container for the heavy-duty engine with a 25-32 quart crankcase capacity.
