HKS engine oils are developed with an idea of that oil is a tuning part to maximize performance of engine. The unique viscosity categorization will effect at molecular level on boundary lubrication. Optimized oil viscosity selection solves hydrodynamic lubrication. Airtightness and friction are highly balanced. HKS as an engine building specialist now offers 100% synthetic special blend oil.
Engine oil is usually used for lubrication of internal combustion engines. The main function of engine oil is lubrication, but also sealing, cooling, cleaning, inhibiting corrosion are other important factors. If one of these factors is lacked by engine oil degradation, the engine malfunction, power loss, fuel economy deterioration are caused leading in the worst case to the engine damage.
To always maintain the normal condition of an engine, regular oil change is required.
