Hydraulic oil is an industrial lubricant used in many applications, from gear pumps to axial piston pumps to heavy-duty farm and industrial equipment. All hydraulic oils should prevent components from excessive wear and maintenance costs. Finally, they should have a minimal impact on the environment.

Luckily, there are products that fit these criteria. Depending on what particular kind of hydraulic fluid you need, there is definitely a good match for you. You just have to know exactly what you want from a hydraulic fluid.

Varieties of Hydraulic Oils

Do you need to operate heavy machinery? Then you should choose a hydraulic oil specially designed for this purpose. This kind of oil will reduce wear, is heat and rust-resistant, and will extend the service life of the fluid and equipment.

Maybe you're looking for an "antiwear" fluid -- one containing additives that inhibit rust, oxidation and foam buildup on your equipment, and thus lower repair costs and downtime. Perhaps your priority is with the environment. Companies such as Amsoil have developed a fluid that addresses that concern: a remarkable, biodegradable synthetic oil that breaks down 80 percent within 21 days.
