LUCAS OIL- SAE 20W-50 BREAK-IN OIL 1 QUART - 10635

Lucas Oil 10635 SAE 20W-50 Engine Break-In Oil is a high-zinc mineral oil designed to protect a freshly built engine during its critical initial start-up period.

- Compatible with ethanol, methanol, and all high-octane racing fuels

- Racing-focused formulation intended for the break-in period only, not for long-term daily driving use
