Meropa XL
Product description
ISO Grade:150, 220, 320, 460
Meropa® XL gear oils are premium high performance synthetic blend gear oils, offering long lubricant life, excellent wear protection with high load carrying capacity and robust micropitting wear protection. They are designed for use in industrial and marine gear systems, where extreme load and shock load protection is required.

Customer Benefits
Meropa XL gear oils deliver value through:
- Provides thermal and oxidative stability — The thermal and oxidative stability of Meropa XL minimizes deposit formation and can extend bearing and gear life. Excellent resistance to oil degradation at high temperatures, resulting in extended oil life and long drain intervals.
- Extended gear and bearing life — Particularly effective in enclosed gear drives operating under extreme load, speed, and temperature conditions.
- Less wear — Ensures optimum wear protection with reduced maintenance and increased system uptime.
Features
Applications
Meropa XL gear oils are recommended for:
- industrial enclosed gearing where an AGMA EP lubricant is specified
- bath, splash, circulating, or spray mist lubrication as applicable to the proper viscosity grade
- marine gearboxes requiring an extreme pressure lubricant
