Rislone Hy-Per Lube ZDDP Supplement, 4405, 11 OZ

Rislone Hy-per Lube Zinc ZDDP Supplement is a petroleum oil performance "booster" containing ZDDP (zinc dialkyldithiophosphate) Zinc and Phosphorous EP (extreme pressure) additives along with mixed esters to help protect internal engine components including pistons, flat tappet camshafts, lifters, pushrod tips and the rest of the valve train. High performance formula stabilizes the motor oil to insure against viscosity and thermal breakdown. Reduces friction & wear, especially at start-up, helping to eliminate dry starts. Less friction means less wear and a cooler running, longer lasting engine. Clinging action keeps bearings and other internal engine parts lubricated where normal oil fails.
