GP-1 Break-In 30W 1 Quart

The GP-1 Break-In 30W 1 Quart motor oil from DRIVEN RACING OIL is specifically designed for the initial hours of a freshly rebuilt or newly installed engine. This break-in oil is essential for allowing piston rings to properly seat against cylinder walls while controlling friction during this critical operating phase. It is ideal for mechanics and engine builders who need to ensure optimal performance during the break-in period.

With a viscosity grade of 30W, this formulation provides a balance between film strength and flow characteristics necessary for fresh engine internals. The 30W weight ensures adequate bearing protection and valve train lubrication while remaining thin enough to minimize resistance during the break-in phase. This oil is designed to help prevent ring stiction and reduce wear during the transition to full-strength lubricants.

Engine builders, automotive hobbyists, and mechanics performing top-end rebuilds on street or track engines will benefit from using this product. It is recommended for use during the first 100 to 500 miles to establish proper ring seal before switching to full-spec racing or street oil. The GP-1 Break-In oil is compatible with both iron and aluminum block engines, making it versatile for various applications.
