TOPGATEX SAE 90 does not have any sulphur/phosphorus additives. The corrosive effects of these products
(at high temperature) on copper or brass alloying synchronizers, or the polishing of steel and molybdenum
synchronizers can strongly hinder the good functioning of gear boxes. This is why some manufacturers
recommend the use of oil at API: GL 1 level in some transmissions.
Very stable viscosity.
Very good protection against wear, corrosion and foam formation.
Excellent resistance to oxidation
