Because of their performance properties, these engine oils can also be used in many other diesel applications. These include stationary generators, fire water pump drives, over-the-road trucks and any other application where a CK-4 is suitable for use.
Unlike other fluids that may lose viscosity when put into service, Komatsu hydraulic oil is shear-stable, meaning it will maintain its original ISO viscosity grade throughout its full service life. Because of its proven performance, this quality fluid can also be used in most hydraulic systems calling for anti-wear hydraulic oil.
Be sure to always consult the OEM manual to comply with fluid selection and maintenance requirements.
