Comp Cams has added a 15W50 lubricant designed specifically for use by professional engine builders during break-in of new and rebuilt engines. With the current government regulations, today’s oils are missing many of the critical ingredients needed for engine protection, forcing engine builders and performance hobbyists to add extra-protection additives in order to maintain engine safety and performance. Engineers at Comp Cams and Endure Performance Lubricants have expanded their line of automotive lubricants to include 15W50 as well as the original 10W30 weight oils. Both popular weights are ZDDP-fortified to provide maximum protection during initial break-in. Mineral-based Comp Cams Engine Break-In Oils are fully formulated and require no additives or supplements. In addition, both popular weights are fully compatible with gasoline, methanol, and high-octane racing fuels. They can be purchased in single quarts, cases of twelve quarts, or pallets of eighty-four cases.
