SLICK 50 Synthetic Engine Treatment (15 oz)

Engine friction robs horsepower and accelerates wear on moving parts, and Slick 50 Supercharged Synthetic Engine Treatment is built to reduce that friction using a full synthetic base oil that meets ILSAC GF5 motor oil specifications. Slick 50 states their Supercharged formula fights friction 18 percent better than the leading synthetic motor oil on its own.

The 15 oz bottle is a pour-and-drive formula — add it to your crankcase at your next oil change and let it circulate with your motor oil. There is no break-in period, no special procedure, and no need to change your oil type. The synthetic base blends with conventional and synthetic motor oils, and the treatment works in automotive, RV, and marine gasoline engines.

Slick 50 has been in the engine treatment category for decades, and their approach with the Supercharged line focuses on reducing metal-to-metal contact at the surfaces where wear actually happens — bearings, cam lobes, cylinder walls, and valve train components. If you are looking for an additive that works with your existing oil rather than replacing it, this is a straightforward option.
