Mobilgrease XHP 100 Mine, 320 Mine, 321 Mine, and 322 Mine are leading members of the Mobilgrease brand of products, which has gained a reputation for innovation and performance excellence. The Mobilgrease XHP Mine Series is designed by ExxonMobil formulation technologists and backed by our worldwide technical support staff.

Mobilgrease XHP 100 Mine, 320 Mine, 321 Mine, and 322 Mine were specifically designed to meet the needs of off-highway and mining equipment that required exceptional EP / anti-wear performance and which would remain in place even in tough conditions of water spray, high sliding, and high temperatures. These greases offer the following features, advantages, and potential benefits:

Features Advantages and Potential Benefits
Excellent EP and anti-wear properties Superb equipment protection and potential equipment life extension even in severe operating conditions
High level of molybdenum disulfide Optimum equipment protection in high sliding mechanisms and with extended re-lubrication intervals
Exceptional resistance to water washout and spray-off Ensures proper lubrication and protection even in hostile work environments
Very good low temperature pumpability and centralized system capability (Mobilgrease XHP 100 Mine and 320 Mine) Provides excellent low temperature pumpability and start-up performance, a key feature for remote applications


Mobilgrease XHP 100 Mine, 320 Mine, 321 Mine, and 322 Mine are recommended for severe off-highway and mining applications in terms of operational severity and water spray. Specific applications include:

  • Bucket pins, pivot pins, and heavily loaded chassis components
  • Heavy equipment central lubrication systems
  • General purpose chassis lubrication
