Mobilgrease 33

Mobilgrease 33 is a high-performance lithium complex grease designed for general-purpose aircraft lubrication. Formulated with 100% polyalphaolefin (PAO) base oils and a premium additive system, it delivers reliable protection across a wide operating temperature range. The advanced formulation provides excellent resistance to thermal and oxidative degradation while maintaining strong structural stability and resistance to water washout.

Its synthetic PAO base oil provides superior low-temperature mobility and low starting torque, making it suitable for demanding aviation applications including anti-friction bearings, gears, actuators, and airframe components. The grease also offers strong wear protection and load-carrying performance in high-pressure environments.

Features and Benefits

  • Wide operating temperature capability with reliable high and low temperature performance
  • Excellent resistance to oxidation and thermal breakdown
  • High structural stability and low oil separation during storage
  • Strong protection against wear, rust, and corrosion
  • Low volatility reducing base oil evaporation in service
  • High resistance to water washout for dependable lubrication in wet environments
  • Extreme pressure performance supporting heavy load applications

Applications

Mobilgrease 33 is a multipurpose aviation grease suitable for highly loaded anti-friction bearings, gears, actuators, and general airframe lubrication. It performs effectively in demanding environments and supports operating temperatures from −100°F to 250°F (−73°C to 121°C). The grease is widely used where aircraft manufacturers specify MIL-PRF-23827 Type I or Boeing BMS 3-33C grease standards.
