All of these products use advanced proprietary formulations designed to provide excellent protection from micropitting fatigue wear, as well as high resistance to traditional scuffing wear. Mobil SHC Gear Series also maintains the latest approvals from OEMs for gear boxes in industrial applications. Mobilgear SHC XMP 320 has long been our recommended oil for lubrication of the main gearbox in wind turbine applications, due to its proven oxidation performance over time. Its durability provides extended drain intervals required for the extreme wind turbine application. Mobil SHC Gear 320 WT is a more recent addition to our Mobil Industrial Lubricant product line and offers an enhancement for wind turbine gear boxes – above and beyond the performance of Mobilgear SHC XMP 320. Mobil SHC Gear 320 WT has improved oxidative stability and higher viscosity index compared to Mobilgear SHC XMP 320, enabling improved low temperature performance and well as oil life.
