Description
Viscol Auto Gear SAE 90 – 85W90 Gear Oil is a premium extreme pressure gear oil developed for demanding automotive and industrial applications. This SAE 90 gear oil delivers reliable lubrication in heavily loaded transmission systems operating under severe conditions.
The 85W90 formulation provides strong load-carrying performance and maintains a stable lubricating film at high temperatures. At the same time, it reduces wear and protects gear surfaces from scuffing under extreme pressure.
In addition, this SAE 90 gear oil offers excellent resistance to oxidation and ageing. These properties help extend oil life and maintain consistent performance over long service intervals. The formulation also includes effective anti-rust and anti-foam protection to support clean and stable gear operation.
Because of its extreme pressure capability, this gear oil performs well in hypoid and helicoidal gear systems. It also helps reduce transmission noise and supports smooth gear engagement under load.
Viscol Auto Gear SAE 90 – 85W90 meets API GL-5 requirements and suits use in automotive differentials, rear axles, gearboxes, and transfer cases. As a result, it is ideal for applications exposed to shock loading and high torque.
Typical physical properties include a density of 0.905 g/mL at 15°C, a viscosity of 198 cSt at 40°C, and 17.6 cSt at 100°C. The viscosity index exceeds 95, while the pour point reaches −21°C, ensuring dependable performance across a wide temperature range.
Selecting the correct gear oil supports transmission reliability and long component life. Therefore, users should always follow manufacturer lubrication recommendations.
