DBR SAE 15W-40 Conventional Diesel Break-In Oil DBR promotes proper surface mating during the critical break-in process and chemically assists with piston ring sealing. A low detergent level 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. Can be used in naturally aspirated and turbo diesel engines. Good for 400 miles of use during the break in period. Viscosity typical of 15W-40. Driven DBR is a Break In oil and should only be used for engine break in. This engine oil will NOT MEET any current API or OEM Engine Oil Specifications as it is formulated specifically for engine break in.
