Mobil passenger-vehicle-lube , Guyana

High Performance Synthetic Multi-Purpose Automotive Gear Lubricant

Product Description

Mobil 1™ Syn Gear Lube LS 75W-140 is a high performance, synthetic, multi-purpose, automotive gear lubricant designed to help meet the highest level performance requirements of many modern passenger vehicles in all types of operating conditions, from mild to severe, 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-140 performs exceptionally over a wide range of temperatures. Mobil 1 Syn Gear Lube LS 75W-140 achieves this through a unique proprietary combination of synthetic baseoils and a precisely balanced additive system that helps to deliver optimized viscosity-temperature properties together with the highest level of inherent formulation stability.  It also helps to protect against thermal and oxidative degradation, wear and corrosion, viscosity loss associated with premature shearing.


Features and Benefits

Mobil 1 Syn Gear Lube LS 75W-140 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. Greater film strength at higher operating temperatures, reduced fluid friction and 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 many sport utility vehicles, vans, light trucks, and cars. This unique, high technology final drive gear lubricant has demonstrated outstanding performance including long-term friction retention, excellent viscosity stability and improved differential/axle durability and cleanliness. Key features and potential benefits include:

     •  Mobil 1 Syn Gear Lube LS 75W-140 is recommended for use in modernigh performance vehicles like sport utility vehicles, vans and light duty trucks requiring API GL-5 performance that require excellent durability

     •  Mobil 1 Syn Gear Lube LS 75W-140 is intended for initial fill, topping-off or refilling differentials, final drives, transfer cases and other gear applications where lubricants meeting API Service GL-5 and multi-purpose or mild EP gear lubricants are recommended

     •  Mobil 1 Syn Gear Lube LS 75W-140 can also be used in rear axles where API Service GL-4 lubricant is recommended

     •  Not recommended for automatic, manual or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended

     •  Recommended for many limited slip applications. For certain high level LS applications, additional limited slip additive may be required if axle chatter is observed.
