The latest break-in oil from Driven Racing Oil™, DBR, is designed for high-performance and turbocharged diesel engines. DBR promotes proper surface mating during the critical break-in process and chemically assists with piston ring sealing, thanks to a proprietary anti-wear formulation that doesn’t rely on conventional friction modifiers. It also features a low detergent level that allows the “fast burn” ZDDP additive to adhere directly to all ferrous metal wear surfaces for maximum scuffing protection of flat tappet cams, bushing lifters, cam driven fuel pumps, turbocharger bearings and cylinder bores.
