subject: Superior Viscosity Of Synthetic Gear Oil [print this page] The viscosity of a fluid can be defined as a measure of it's resistance to flowing and commonly known as it's thickness or stickiness. Gear oils tend to be thicker or more viscous than other oils, such as motor oil, because they need to stick to gears during their rotation and protect gear teeth from wear while engaging. If gear oils are too thin, they will not protect the faces of gear teeth from metal on metal wear. If gear oils are too thick, they will create viscous drag, energy inefficiencies, and poor performance during component operation. can be created with the precise viscosity levels necessary for superior protection and performance. This is because, like other synthetic fluids, it is created by engineers in a laboratory to supply specific, chemical properties and molecular uniformity. hold their viscosity levels over time far better than traditional gear oils as well.
Viscosity is what allows gear oils to protect gear teeth faces from wear during operation. Viscous fluids stick to gears during their many revolutions and create a thin layer of protection between gear teeth. Conventional, petroleum based fluids break down quickly under extreme temperature spikes, losing their viscosity and strength between drain intervals. This molecular breakdown and viscosity loss can be very detrimental to gear teeth when under heavy loads. It will lead to unnecessary metal on metal wear, fluid contamination, and ultimately result in premature part failure.
last longer than traditional oils, hold their viscosity levels better, and therefore, better protect gears from wear during the intense pressures and temperatures experienced inside differentials and manual transmissions. They also contain anti-wear and extreme pressure additives as well as detergents in order to better protect and clean the metals used in these components.
The viscosity index of gear oil can change in extreme temperatures. It will get thicker in extreme cold and thinner in extreme heat. also contain viscosity index improver additives to withstand temperature extremes for better protection. One of the more popular lines of on the market is Severe Gear. It is produced by one of the oldest, most respected, and well known companies amongst synthetic fluid producers. This line tested well against many other gear oils when considering several aspects such as thermal runaway, shear stability, viscosity index, and viscosity protection. Severe Gear synthetic gear lubes are good examples of the superior protection, preservation, and performance that can provide an automobile's differential or manual transmission.
