HKS Super Oil series were developed on the concept of "engine oil is one of the engine part". HKS' original "HIPER ESTER" can follow extreme boundary lubrication to any kind of engines on the metal absorbed molecular level. Each engine oil viscosity was determined specifically for the target engine for optimum engine performance. Super Oil is 100% specially blended synthetic oil.
RB25/RB26 engine is the basic of inline 6-cylinder engines. This oil can improve the drivability at mid-range rpm and capability to control high temperature and shear property associated with explosive output increase at high-range rpm. Super Oil RB is the best to use for the RB25/RB26 engine to maximize the engine characteristics.
Typical Application: Skyline GT-R, Skyline, etc
