Mobil Delvac Xtreme Grease Moly 1 & 2 are both manufactured with a proprietary, high-temperature lithium complex thickener system. They exhibit excellent resistance to softening under severe working, and provide good adhesion and cohesion. A 2-phase extreme-pressure additive system provides exceptional 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. These heavy-duty, severe-service greases have outstanding structural stability and chemical stability, will not corrode steel or copper bearing alloys, and are compatible with conventional seal materials. Mobil Delvac Xtreme Grease Moly 1 and Moly 2 are fortified with 3% moly (that is, molybdenum disulfide) to provide enhanced Extreme Pressure (EP) and Anti-wear (AW) protection in heavily loaded and high sliding applications.
