Mobil Delvac Xtreme Grease 

Mobil Delvac™ Xtreme Grease

Mobil Delvac™ Xtreme Grease is an extra high performance extreme-pressure grease. It is an NLGI 2 grade and is manufactured with a proprietary, high-temperature lithium complex thickener system. It exhibits excellent resistance to softening and provides good adhesion and cohesion. An extreme-pressure additive provides excellent protection against wear and shock loads, while additional additives enhance resistance to high-temperature oxidation and protection against rust. Other formulation features provide very good resistance to water wash, and long service in bearings operating at high temperatures. This heavy-duty, severe-service grease has outstanding structural stability and chemical stability, will not corrode steel or copper bearing alloys, and is compatible with conventional seal materials.

Mobil Delvac Xtreme Grease is recommended for use in heavy-duty trucks, especially hinge and bucket pins, U-joints, and fifth wheels. It is also recommended for construction and mining sector applications, particularly for the lubrication of plain and antifriction bearings in contractor and mining vehicles working under severe operating and weather conditions. Mobil Delvac Xtreme Grease is also recommended for use in heavily loaded industrial bearings. The recommended application temperature range is -20°C to +175°C.

Mobil Delvac Xtreme Grease is designed by our formulation technologists specifically to meet the needs of customers with heavily loaded equipment that requires high extreme-pressure/antiwear performance and stay-in-place performance even in tough conditions where water wash, high sliding, and high temperature conditions are present:

FeaturesAdvantages and Potential Benefits
Excellent resistance to water, including spray off and wash outMaintains excellent lubrication properties and protects equipment in conditions of water contamination
Outstanding extreme-pressure and antiwear protectionLower maintenance costs and less unanticipated downtime
Better stay-put properties at high temperaturesExcellent performance in high shear, high load applications, especially where grease re-supply is limited
Excellent resistance to rust and corrosionProtects equipment in the presence of water for reduced maintenance and longer equipment life

 

Recommended by Imperial Oil for use in:

  • Heavy-duty trucks, especially hinge and bucket pins, U-joints, and fifth wheels
  • Mining and construction equipment
  • Highly loaded plain and antifriction industrial bearings
