Mobil 1™ Synthetic Gear Lube LS

Outstanding power transfer performance

Mobil 1 Synthetic Gear Lube LS is a supreme performance, synthetic, multipurpose, automotive gear lubricant designed to:

  • Meet or exceed the highest level of performance requirements of many modern passenger vehicles – including limited slip applications
  • Help protect against thermal and oxidative degradation, wear and corrosion, and viscosity loss associated with premature shearing
  • Help promote outstanding power transfer performance – even in some of the most severe driving conditions

Through a proprietary formulation of synthetic base oils combined with a unique additive system, Mobil 1 Synthetic Gear Lube LS performs exceptionally across a wide range of temperatures compared to conventional hypoid gear lubricants.
