Item Package Quantity:1 A robust conventional motor oil to be used where frequent oil changes are needed, such as in dirt track and sportsman bracket racing, to eliminate the build-up of dirt or fuel dilution. It utilizes a proprietary anti-wear and friction-reducing additive package to fight valve train wear and internal scuffing. Ideal for race engines requiring a 20W-50 weight motor oil, SR50 provides consistent protection for flat tappet engines and prevents lifter skidding in aggressive roller cam valve trains using both needle and bushing lifters. It is not recommended in engines with stamped steel rockers; instead, use Driven Racing Oil's XP9 or XP6 for optimal durability.
