HKS OIL SERIES are all 100% synthetic.

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.

HKS bestseller engine oil series “SUPER OIL” are refined with an additive made by the latest technology that fights against LSPI(Low Speed Pre-Ignition).

• Effective against LSPI(Low Speed Pre-Ignition)
  HKS bestseller engine oil series “SUPER OIL” are redesigned by the latest technology; an additive was prescribed and added to the oil to protect the engine against the effects of LSPI (Low Speed Pre-Ignition) which tends to occur to a downsized turbocharged engine.
  Usually, LSPI occurs when low viscosity engine oil is used to a downsized turbocharged engine; however, even high viscosity engine oil is used, if the engine is a high compression and high boost tuned direct injection turbocharged engine, and it is run under severe combustion condition, LSPI may occur. New “HKS SUPER RACING” series are the unprecedented high viscosity engine oil that can protect the engine from LSPI.
