Petroleum Break In Oil 30w 1 Qt

Lucas Oil Petroleum Break In Oil 30W in a 1-quart bottle is a specialized motor oil formulated specifically for the break-in period of engines. This oil is ideal for small-block and mid-block gasoline engines during their first 500–1,000 miles of operation, as well as classic vehicle restorations that require high-ZDDP protection.

The high zinc content in this oil, primarily in the form of zinc dialkyldithiophosphate (ZDDP), provides essential anti-wear protection during the critical initial operation phase. The 30-weight viscosity ensures reliable film strength and controlled flow to critical engine components, helping to establish proper operating surfaces while resisting thermal breakdown.

This product is particularly beneficial for new engines and those undergoing restoration, where vintage specifications call for straight-weight oils. The convenient 1-quart size is perfect for top-off maintenance or testing during the break-in process, ensuring that your engine receives the protection it needs during this crucial time.
