Castrol® AP (all purpose) Gear Lubricant™ is a multi-purpose, extreme pressure gear oil that has superior thermal durability and will provide transmission, differential and other application protection beyond that specified for the current SAE J2360 (formerly MIL-PRF-2105E), API GL-5 and API MT-1 (80W-90) requirements. Its thermal durability extends component life and reduces critical component wear.
Castrol AP Gear Lubricant helps you to:
- Promote efficient gear operation by balancing low and high temperature viscosity
- Prevent metal-to-metal contact by maintaining a sufficient oil film between the parts
- Prevent rust and reduce friction through its optimized formulation
- Protect gears from deposit buildup under the stress caused by hauling extra-heavy loads with our thermally durable additive system, which resists oxidation and deposits
- Lengthen component life with wear protection that far exceeds industry requirements
