Gearex 90 and 140 gear oils are produced with conventional mineral base oils and additives and are formulated for manual automotive transmission systems. It is produced for use in axles, differentials and gearboxes of trucks, buses, light commercial vehicles and other normal powered machines without excessive pressure. In addition, API: GL-1 level oil can be used in recommended places in machinery working in construction, mining and agriculture works outside of highways.
BENEFITS
• It provides effective protection against wear of gears operating under normal load.
• It also protects the non-ferrous parts of the system against rust and corrosion.
• It prevents deposit formation thanks to its good thermal and oxidation stability.
• Compatibility with superior seals minimizes the chance of leaking into the environment.
• An GL-1 oil can also be used in other recommended gearboxes.
