Castrol Limited Slip Gear Lubricant is an extreme pressure, multipurpose gear lubricant that is friction modified to meet the requirements of many limited slip differentials. Castrol Limited Slip Gear Lubricant is thermally stable and will provide transmission, differential, and other application protection beyond the current API GL-5 requirements. This thermal stability extends oil service life and reduces critical component wear.

Note that some equipment manufacturers will mandate the use of their Limited Slip type product or recommend that only a special additive be added to an API GL-5 gear lubricant.
