BRAD PENN PENN-GRADE 1 SAE 30 Break-In Oil is a unique mono grade racing engine oil, formulated with a blend of high quality Penn Grade base oils and special additives. Highly recommended for use during the break-in cycle for newly rebuilt engines..

Without proper oiling, new surfaces of rings, cylinder walls, camshafts and bearings will be compromised and performance diminished. The slippery properties of synthetic racing oils do not let the new parts make enough friction to mate properly.  No oil off the retail shelf contains the protective additives needed to prevent excessive wear and galling of new parts. Just like a new baby needs mother's milk for a while, brand new engines need to start out on a special formula oil to grow up big and strong.  An absolute must for the serious engine builder.
