Driven Racing Oil announces the addition of DI50 to its lineup of Direct Injection Motor Oils. DI50 is a full synthetic motor oil specifically formulated for high-performance direct injection engines requiring a 15W-50 viscosity, such as late model GM Gen V (LT1, LT4, LT5) engines where GM specifies a 15W-50 viscosity for track-use. DI50, as with the other lubricants from Driven?s recently launched Direct Injection Motor Oil line, were specially engineered to solve low speed pre-ignition issues that occur under load in high-performance direct injection engine applications. These DI oils feature an advanced additive package that reduces the occurrence of abnormal combustion events, and soot suspending additives that reduce soot-induced wear. These lower volatility base oils also reduce the amount of crankcase vapors and, thus, carbon buildup on intake valves.
