Lucas Oil 10636 Sae 20w-50 Break-In Oil

Lucas Oil 10636 SAE 20W-50 Racing Break-In Oil is specifically engineered to protect new engines during the critical break-in period. This high-zinc formula helps seal new piston rings while delivering exceptional extreme pressure protection for the entire valve train, camshaft, and other critical engine components.

Key Features:

• High zinc content (approximately 3600 PPM) provides superior wear protection compared to standard passenger car oils
• Specially formulated for flat tappet camshafts and high-performance racing applications
• SAE 20W-50 viscosity grade suitable for most break-in procedures
• Advanced extreme pressure additives protect valve train components during initial engine start-up
• Promotes proper ring seating for optimal compression and oil control

This break-in oil is designed exclusively for racing and performance engine applications. It should be used during the initial break-in period and then replaced with your preferred racing oil. Not suitable for modern passenger vehicles requiring API service classifications due to elevated zinc and phosphorus levels.
