Castrol ST90 Monograde API GL3

Description •Monograde SAE90 gear oil •For gearboxes and differentials where a non low EP gear oil specified •For straight cut gears •API GL-3 Classic ST 90 is a gear oil formulated with high quality mineral oils. It is fortified with an anti-oxidation and anti-wear additive to ensure that the oil is able to withstand the oxidising conditions which are present in gearboxes/axles during service and to ensure that the gear teeth are protected against wear. Application Classic ST 90 is suitable for the lubrication of most types of gears including helical, spur, bevel and worm; but must not be used for hypoid gears where API GL-4 or GL-5 oils are recommended. The type of additive system used makes it particularly suitable for use in older vehicles where the lubricated application may contain sensitive metal (yellow) components (eg. brass/bronze).
