FAQ:

Q: What is gear oil works best for You?

A: Gear oil is used as a lubricant between the moving parts of a gear system so that the gears mesh and turn smoothly. Depending on the type of gears and the operation conditions the gear oil will need to possess different physical properties to adequately lubricate and protect the gears. The measure of the thickness of a liquid is called viscosity.

Q: What is the difference between gear oil and motor oil?

A: Gear oil differs from motor oil. While many motorists may assume SAE 90 gear oil is thicker than SAE 40 or 50 motor oil, they are actually the same viscosity; the difference is in the additives. Motor oil contains additives such as detergents and dispersants to combat byproduct chemicals from gasoline or diesel ignition.

Q: What gear oil do you use?

A: Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears. Light grade oil is ideal for small, fast, polished gears under a light load. Heavy grade oil is suited for large, slow, rough gears under a heavy load. Check your manufacture’s specifications for the gear grade needed in your equipment.

Q: What are the types of gear oil?

A: There are essentially two different types of synthetic gear oil, polyalphaolefin (poly-alpha-olefin), or PAO and polyalkylene glycol, or PAG. PAO oils are, in fact, enhanced versions of regular mineral oils and can be mixed freely with them.
