Description
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).
