ENGINE SPECIFIC OIL

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.

JZ-G(10W50)

JZ-G series are high rigidity and compact inline 6-cylinder engines.

Achieving high performance controlling delicate but dynamic engine characteristics is the target to develop this oil. The optimized oil viscosity for the JZ-G engine overcame the high boundary lubrication and brought out high performance at high engine RPM and output.

RB(15W55)

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 RB26 engine to maximize the engine characteristics.


EVO-X(3.5W37)

The best to use for the 4B11 engine on Lancer Evolution X, Galant Fortis Turbo, etc.

HKS' original "HIPER ESTER" can follow extreme boundary lubrication of any kind of engines on the metal absorbed molecular level. The optimized oil viscosity for the 4B11 engine enables the use of this oil under higher load. Airtightness and friction balance of this oil are maintained at high levels.

4G63(5.5W38)

4G63 is the best to use for the 4G63 engine.

4G63 engine is built with the highly reliable cast-iron engine block.The optimized oil viscosity for the 4G63 engine can bring out more of advantages of the long stroke design and the engine characteristics that created by the unique turbo system. Quick response at the moment of stepping on the accelerator can be experienced.


EJ(7.5W42)

EJ engine is the big bore/short stroke horizontal opposed engine

This unique system requires reducing mechanical abrasion and equalizing oil lubrication to all area. The optimized oil viscosity for the EJ engine can support torque improvement as well as engine protection by the oil film retainment ability of HIPER ESTER's metal absorbed molecule. Super Oil EJ is the best to use for the EJ engine.

13BT(10W45)

13BT is the best to use for the rotary turbo engine

100% synthetic oil can prevent carbon from adhering to inside the housing that usually occurs in a rotary engine. HIPER ESTER maintains the oil film retainment under high temperature and airtightness inside the housing without risk to the rotary engine apex seals.


HR(-4W31/0W42)


The target engine for HKS Super Oil HR series is the most-advanced NA engines. Friction reduction can be experienced under various driving stages from daily driving to circuit driving. Oil viscosity resistance is reduced while maintaining the oil film to run the engine without any stress.
HKS Super Oil HR series is a replacement of "Premium Pro OIL" and "RACING Pro OIL." -4W31 is equivalent to API standard 0W30. Low viscosity at the regular use range from 40℃ to 100℃ can improve the engine response. Also, the engine condition at the high load range is highly maintained.0W42 is multi-grade type. This type is recommended not only for NA engines but also GT Supercharger installed vehicles.
