A dispersion of thickening agents in a liquid lubricant produces grease, a solid or semisolid lubricant. Typically, grease is made out of soap that has been emulsified with mineral or vegetable oil. A frequent characteristic of greases is that they have a high initial viscosity that, when subjected to shear, decreases to create the impression of an oil-lubricated bearing with a viscosity that is roughly equal to the base oil used to make the grease.

A lubricant manufactured specifically for differentials, transfer cases, and gearboxes in cars, trucks, and other machinery is known as gear oil. It typically contains organosulfur compounds and has a high viscosity.

The medium via which power is conveyed in hydraulic machinery is known as a hydraulic fluid or hydraulic liquid. Mineral oil or water are the main ingredients in most hydraulic fluids.
