Lucas Oil 10631 SAE 30W Break-In Engine Oil - 5 Quart

Lucas Oil SAE 30W Break-In Oil is specifically formulated for the critical initial start-up period of new or rebuilt engines. This specialized motor oil promotes faster, more efficient piston ring sealing to maximize compression and power output from the first fire-up. The unique formulation is compatible with ethanol, methanol, and high-octane race fuels, making it ideal for both street performance and racing applications.

Key Features:

• Accelerates piston ring seating for quicker break-in and improved compression
• Elevated zinc and phosphorus (ZDDP) levels provide maximum protection during critical break-in phase
• Essential for flat tappet camshaft break-in to prevent premature cam lobe and lifter wear
• Reduces blow-by for increased power and better ring seal
• Complete formulation requires no additional moly supplement or additives
• Recommended for initial break-in of both flat tappet and roller camshaft engines
• Excellent for on-track performance testing before switching to conventional or synthetic racing oils
• SAE 30 weight viscosity optimized for break-in procedures

This 5-quart container provides enough oil for most engine break-in procedures. Follow manufacturer recommendations for break-in duration before switching to your preferred racing or performance motor oil.
