Red Line Break-In Oil 40 – Quart (High-Zinc Conventional Break-In Motor Oil)
The Red Line 16004 Break-In Oil 40 is a specialized high-performance conventional 40-weight break-in motor oil engineered for new or rebuilt engines. Formulated with an extremely high level of ZDDP (2900 ppm Zinc and 2600 ppm Phosphorus), it provides maximum protection for flat tappet camshafts, lifters, and valvetrain components during the critical initial break-in period. This oil requires no additional additives and is specifically designed to help seat piston rings while preventing metal-to-metal contact under high-load conditions. Ideal for race engines, performance builds, and any engine requiring a dedicated break-in oil before switching to synthetic or high-mileage formulas.
