HKS Super Oil series were developed with the concept of "engine oil is one of the engine parts".

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.

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 is the best to use for its specifically labelled engine to maximize the engine characteristics.
