Shell Transmission Oil MA 75W-90
Shell Transmission Oil MA 75W-90 is a fully synthetic high-performance gearbox oil developed to meet the demanding lubrication requirements of modern heavy-duty transmissions. Formulated using advanced synthetic base oils and specialised additive technology, Shell Transmission Oil MA 75W-90 provides reliable protection, smooth gear operation and long service life in demanding drivetrain applications. The formulation is engineered to deliver stable viscosity, strong wear protection and dependable lubrication across a wide operating temperature range.
One of the key advantages of Shell Transmission Oil MA 75W-90 is its excellent thermal stability and durability under high load conditions. Modern heavy-duty transmissions often operate under severe mechanical stress and elevated temperatures, which can lead to lubricant breakdown and reduced component protection. Shell Transmission Oil MA 75W-90 uses advanced lubricant technology to maintain stable performance even at high operating temperatures, helping protect gears and transmission components from wear and damage.
Shell Transmission Oil MA 75W-90 also provides excellent gear protection in demanding operating environments. The advanced additive system forms a durable lubricating film between gear surfaces, helping reduce metal-to-metal contact and prevent wear under high loads. This protection helps extend the service life of transmission components while maintaining reliable gearbox performance throughout the lubricant’s service interval.
Another important benefit of Shell Transmission Oil MA 75W-90 is its ability to support smooth and consistent gear shifting across a wide range of temperatures. The carefully balanced viscosity characteristics allow the lubricant to provide good fluidity at low temperatures while maintaining a stable lubricating film at higher operating temperatures. This helps ensure smooth gear engagement during cold starts while maintaining effective lubrication during heavy-duty operation.
Shell Transmission Oil MA 75W-90 also offers extended oil drain capability. The formulation’s strong oxidation resistance and ability to reduce operating temperatures help maintain lubricant performance over longer service intervals. This extended oil life helps reduce maintenance requirements and contributes to lower operating costs for vehicle fleets and equipment operators.
Shell Transmission Oil MA 75W-90 is particularly suitable for heavy-duty manual transmissions fitted with synchromesh systems operating under severe load conditions. The lubricant is designed to meet the latest Mercedes-Benz heavy-duty transmission requirements and is approved under MB-Approval 235.21 and DTFR 13B110. It may also be used in certain passenger car gearboxes and transaxle designs where an API GL-4 specification lubricant is recommended.
Physical characteristics include a kinematic viscosity of approximately 96 mm²/s at 40°C and 14.6 mm²/s at 100°C with a viscosity index of approximately 158. Shell Transmission Oil MA 75W-90 has a density of approximately 847 kg/m³ at 15°C, a flash point of around 215°C and a pour point of approximately −42°C, supporting reliable lubrication performance across a wide range of operating conditions.
