Torco ZEP contains MPZ®, a perfect balance of zinc, phosphorus and moly. The friction 
fighting chemistry of MPZ® adds wear protection back into motor oils that have “zinc”, the 
anti-wear chemical, purposely removed. ZEP won’t rub off, wear off, scrap off or scuff off. 
For this reason, it is excellent for high-performance engines, especially those with flat 
tappet cams. ZEP coats all engine parts and protects them from “dry starts,” a leading 
cause of engine damage in vehicles kept in storage and driven infrequently.
