VPS Gear Oil is a superior sulfur-phosphorus extreme pressure gear lubricant formulated with synthetic basestocks and additives to provide excellent performance. It is designed to provide excellent extreme pressure protection, load carrying capacity, anti-foam performance, corrosion protection, and thermal stability protection. It is recommended for conventional and high performance applications. VPS Gear Oil is recommended for use in axle applications requiring factory-fill or servicefill levels of limited slip performance without the need to add extra limited-slip (LS) additive. VPS Gear Oil 75W-90 and 75W-140 meet API GL-5 specifications and are recommended for use in axle applications requiring
factory-fill or service-fill levels of limited slip performance. VPS GearOil 75W-140 is also recommended for use where Ford M2C-192A, GM 12346140, Chrysler MS-8985 SAE 75W-140 gear oil is specified. The addition of a supplemental LS friction modifier (Ford M2C-118-A, Chrysler MS-5630, or GM 1052358) is not required. The unique VPS Gear Oil formulations have been tested with multiple differential clutch materials and at different temperatures to provide the best solution for a LS containing gear oil. The combination of additives in VPS Gear Oil is unlike any other Valvoline gear oil with respect to performance in LS differentials.
