It is a popular misconception that all you need for breaking in a new or freshly rebuilt engine is a cheap, low quality motor oil. During break-in the engine needs to seat the rings to the cylinder walls and, in the case of a flat tappet valvetrain, mate the lifters to the cam lobes. So the idea is the poor lubrication qualities of the cheap oil will allow that wear that’s necessary to break in an engine to happen more quickly.
But there’s a big difference between lubrication and protection, and protection is something you never want to give up for your engine–no matter what. That’s why a quality break-in oil for new high-performance motors is so critical. A well designed break-in oil formulation will reduce the amount of lubrication while still providing optimum protection to critical engine components during the very stressful break-in period.
New BR40 Break-In Oil from Driven Racing Oil is specially formulated to provide your engine with the proper foundation for maximum durability and performance during the critical break-in period.
Driven’s new BR40 Break-In Oil features a conventional 10W-40 viscosity that’s perfect for many flat-tappet stock car racing engines. BR40 not only delivers maximum scuffing protection, it also contains an anti-wear formulation that doesn’t rely on friction modifiers, which helps promote proper ring seating. Ideal for use in flat tappet and aggressive roller cam engines, the BR40 blend is formulated to improve ring seal without increasing wear, and is good for dyno testing or a night of racing if you are going straight to the race track. With no Zinc (ZDDP) added, the BR40 Break-In Oil is best used with Ethanol-blended fuels, pure Methanol fuels and oxygenated race fuels. Just combine BR40 with a proper break-in procedure, and you can be sure that you’ve done everything required to ensure both maximum engine performance and service life.
