Castrol ST90 is a monograde SAE90, API GL-3 gear oil for gearboxes and differentials requiring a low EP gear oil.
Castrol ST90 is formulated from high quality mineral oils and fortified with anti-oxidant and anti-wear additives, to ensure the oil is able to withstand the oxidising conditions which will be present in the gearbox during service.
Castrol ST90 is suitable for the lubrication of most types of gear including helical, spur, bevel and worm but most not be used for hypoid gears which require extreme pressure lubricants.
