GP-1 30W Break-In Oil Case 12 x 1 Quart

The GP-1 30W Break-In Oil Case from DRIVEN RACING OIL is specifically designed for the critical first miles of newly rebuilt or freshly machined gasoline engines. This break-in oil is essential for ensuring proper ring seating and protecting freshly honed cylinder walls and new bearing surfaces. It is ideal for use in fresh short-blocks, new crate engines, or heavily modified powerplants with new internals.

This 30-weight break-in formula is engineered to balance viscosity, detergent levels, and anti-wear additives, promoting optimal ring-to-wall contact during the initial break-in period. The formulation allows for controlled ring seating without over-protecting, as a thinner oil film encourages the necessary mechanical contact for proper compression and seal integrity. The 30W viscosity reduces drag on fresh pistons and rings while maintaining adequate film strength on newly finished bearing surfaces.

Engine builders and performance shops will find this product particularly beneficial during the first 500–1,500 miles of operation. The case contains twelve 1-quart bottles, providing a total of 12 quarts for a complete break-in cycle, drain interval monitoring, and top-offs during the critical bedding period. This formulation is adaptable for various applications, making it a versatile choice for performance and street use.
