Royal Purple Heavy Duty Motor Oil

Royal Purple® HD Motor Oil is specifically formulated to maximize performance and meet the demands of heavy-duty engines.  Many older heavy-duty engines, and some newer commercial and stationary engines recommend the use of heavy-duty engine oil with a high level of anti-wear additive (ZDDP), and heavier viscosity grades. HD Motor Oil is fortified with a high level of zinc/phosphorus anti-wear additive and a generous dose Synerlec®.
