Red Line Engine Break-In Additive (Set of 12 x 16 Oz.) 81403

Red Line Engine Oil Break-In Additive is formulated to enhance the protective qualities of conventional motor oils during the critical engine break-in period. It supplements the oil with anti-wear additives, particularly zinc and phosphorus (ZDDP), which are essential for safeguarding camshafts and valvetrains from excessive wear. This additive is particularly valuable for engines featuring high-performance camshaft grinds and strong valve spring pressures, which are common modifications. Red Line Engine Oil Break-In Additive also promotes proper piston ring seating while minimizing wear on other engine components. A single 16-ounce bottle treats up to 12 quarts of motor oil, potentially lasting through two engine break-in periods or oil changes. Notably, this additive can be used with both conventional and synthetic oils during regular operation, offering an additional layer of protection not typically found in standard motor oils.
