Lucas Oil 10630 SAE 30W Break-In Motor Oil

Lucas Oil 10630 SAE 30W Break-In Oil is a high-performance engine oil specifically formulated for the critical break-in period of freshly rebuilt or new engines. This specialized racing oil 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 at approximately 3,600 PPM ZDDP?significantly higher than modern passenger car oils
• Specially designed for flat tappet camshaft break-in applications
• SAE 30W viscosity grade suitable for a wide range of engines and operating conditions
• Excellent extreme pressure properties protect against cam lobe and lifter wear
• Promotes proper piston ring seating during initial engine operation
• Formulated specifically for racing and high-performance applications

This break-in oil provides the extra wear protection needed during the critical first hours of engine operation when metal-to-metal contact is most severe. The elevated zinc and phosphorus levels offer superior protection for flat tappet camshafts and other valve train components that are vulnerable during break-in. Recommended for racing applications only?not suitable for passenger vehicles requiring API-certified service oils.
