Mobil 1™ Synthetic Gear Lubricant 75W-90
Mobil 1™ Syn Gear Lube LS is a superior performance, synthetic, multi-purpose, SAE 75W-90 automotive gear lubricant designed to help meet the highest level performance requirements of modern passenger vehicles in all types of operating conditions including limited slip applications, as well as, deliver outstanding power transfer performance. Compared to conventional hypoid gear lubricants, Mobil 1 Syn Gear Lube LS 75W-90 performs exceptionally over a wide range of temperatures. Mobil 1 Syn Gear Lube LS 75W-90 achieves this through a unique proprietary formulation, that deliver optimized viscosity-temperature properties together with the highest level of inherent formulation stability and helps to protect against thermal and oxidative degradation, wear and corrosion, viscosity loss associated with premature shearing. It also can be used in extended service and for aiding in fuel economy performance.
Features and Potential Benefits
Mobil 1 Syn Gear Lube LS 75W-90 combines wax-free synthesized hydrocarbon base oils and a specially designed extreme-pressure, limited-slip, sulfur-phosphorous additive system to help provide a significantly higher level of performance in rear axles and differentials versus conventional fluids. Great film strength at higher operating temperatures reduced fluid friction and low-temperature application down to -40°C helps to provide significant advantages versus conventional mineral oil formulations. It helps to reduce wear and spalling under the high speed, high torque and high horsepower conditions in competitive racing and high performance automobiles. This unique, high technology final drive gear lubricant has demonstrated outstanding performance including fuel economy, extended drain, long-term friction retention, low-temperature capability and improved differential/axle durability and cleanliness. Key features and potential benefits include:
| Features | Advantages and Potential Benefits |
| Exceptional thermal stability and resistance to high temperature oxidation | Helps to extend gear and bearing life due to minimal deposits Long seal life Potential extended oil drain/service intervals |
| Outstanding protection against low speed/high torque wear and against high speed scoring | Capability to handle some of the severest driving conditions while delivering smooth efficient and reliable performance |
| Exceptional shear stability | Helps to retain viscosity and film strength under severe operating conditions to prevent wear |
| Excellent rust, staining and corrosion protection of copper and its alloys | Helps to reduce wear Long component life |
| Enhanced frictional properties | Improved fuel economy and reduced operating costs |
| Outstanding low temperature fluidity versus mineral oils | Helps to reduce wear at start up and ease of start-up even in arctic conditions |
| Good resistance to foaming | Helps to maintain film strength for reliable lubrication |
| Compatible with typical automotive seals and gaskets | Helps to minimize leakage and reduce contamination |
| Excellent limited-slip performance | Helps to reduce chatter and improve traction |
