There are industry standard specifications for engine oils, gear oils, hydraulic oils, turbine oils, etc. Standardized specifications are wonderful for the end user, simplifying product choice and ensuring a certain level of performance. This also facilitates cross-referencing, and ultimately, a degree of product commoditization. Greases are different. There have been
The history of lubricating greases dates back to ancient times. As early as 1400 BCE, attempts were made to reduce axle friction in chariots. Analyses from axel hubs indicate that fat and lime were used to make a complex lubricant. Yet, the current state of lubricating greases only has less
Lubricating greases are complex products, consisting of a lubricating fluid, performance enhancing additives and a thickener. The lubricating fluid can be mineral oil, synthetic fluid of various types or even processed vegetable oil. The viscosity of the fluid can range from very low (ISO 10 or less) to very high
Mobilgrease XHP™ 222 grease is now approved against the NLGI HPM certification! In addition to the HPM core certification, Mobilgrease XHP™ 222 also obtained the +WR tag for enhanced level of performance in the water resistance category. The HPM Grease Certification Program ensures that all certified greases meet or exceed
“The field of electric vehicle (EV) grease formulations is evolving,” says STLE member Anoop Kumar, senior staff scientist and subject matter expert on grease formulations at Chevron Technical Center in Richmond, Calif. Grease formulations for EVs are just one of the many changes shaking up today’s automotive industry, but getting

Because grease is so poorly understood, there are many myths surrounding grease quality. Some examples include: “block grease is better,” “sticky grease is better,” “red grease is the best,” “greases with different thickener type are always incompatible,” “good greases don’t bleed oil,” and “multi-purpose greases are all the same.” Read
The NLGI high-performance multiuse (HPM) grease specification (NLGI, Liberty, MO, nlgi.org) will play a significant role in industry in the coming years, providing a baseline performance indication for lubricating greases and a guide for optimizing solutions through various grease technologies.
