Mobil grease 28 Synthetic Aircraft Grease Red 13.4oz Tube

Wide-temperature protection. Proven aviation performance.

A high-performance synthetic grease designed for demanding aircraft and industrial applications.

Mobilgrease 28 is a synthetic, antiwear grease formulated with a polyalphaolefin (PAO) base fluid and organo-clay thickener. Designed to perform across a wide temperature range, it provides excellent low-temperature operation while maintaining stability under high-temperature and high-load conditions.

Widely used in military and civil aviation, Mobilgrease 28 is suitable for bearings, actuators, screw jacks and other mechanisms requiring reliable lubrication with minimal friction and wear.

Key Features:

• Excellent performance across a wide temperature range
• Very good low-temperature pumpability
• Low starting and running torque
• High thermal and oxidative stability
• Excellent load-carrying and antiwear performance
• Helps reduce frictional drag
• Resistant to water washout
• Suitable for high-speed and high-temperature bearings
• Effective for heavily loaded sliding mechanisms
• Synthetic, wax-free PAO base fluid
• High dropping point of approximately 300°C
• Proven history in military and aviation applications
