Full Description
Driven break-in mineral oil is a low-detergent, high-ZDDP formulation designed to protect an engine during the critical running-in period. It will protect all types of the valve train, including those using very high spring pressures and also help create the best ring seal in the block, which is key to good compression figures.
Effective running-in can be achieved by up to two hours on the dyno/competition use or 500 road miles.
Available in 5W-30, 10W-40 and 15W-50 grades.
We recommend that you run the engine at 1,800-2,200 rpm for around 30 minutes on the dyno then let it cool. Continue with full power pulls, as it is important to build cylinder pressure to get the piston rings to seal. If the engine is installed in a car, follow the same principle, but after the initial 30 minutes of steady engine speed and full acceleration runs, continue to run at modest loads for around 500 miles before changing the oil. Please note: The engine will smoke through the valve cover breathers when the BR oils are used. This is due to the light end base oils that are designed to burn to aid the piston ring sealing.
