The transmission, transfer cases, differentials and gear boxes in cars and trucks contain a series of gears and bearings. These keep moving and come into contact with each other while converting the torque into power and transferring it to through the drive shaft to the axles. The gears intertwine every time the clutch engages and disengages as the vehicle changes acceleration.
In short, there is a lot of rolling, sliding, grinding and other violent action going on in the shafts and gears. This is bound to generate a lot of heat and friction which will cause untold wear and tear on the teeth and other metal surfaces until they finally destroy each other.
Lubrication is essential to both promote easy movement and control the increase in temperature. And this is where gear oil enters the picture.
As the name goes, gear oil is specifically designed to protect the gear sets and keep them working cohesively and efficiently. It has a higher viscosity than regular engine oil which allows it to stick to the moving parts and keep them lubricated properly. The oil forms a film on the various metal surfaces and keeps them apart while they work together to deliver optimum power output and keep the vehicle running smoothly. For certain applications, the gear oil is fortified with extreme pressure (EP) and anti-wear additives to deliver increased protection.
Gear oils do not come into contact with the gases, acids and other pollutants like engine oil. Therefore, they can last much longer and have an extended change interval. However, the gear oil is also bound to get contaminated with moisture and debris which can discolor the oil or make it more viscous. As the gear oil breaks down, the increased friction can cause difficulty in engaging gears and damage the components as well. Left unchecked, it can entail a costly overhaul.
Therefore, regular checks and changing the gear oil based on the manufacturer’s recommendation is crucial.
There are a variety of gear oils in the market and in general, synthetic gear oils deliver greater resistance to shear breakdown than mineral oils. Gear oils are further classified by the American Petroleum Institute using GL ratings ranging from GL1 to GL5. The higher the oil’s GL rating the greater pressure it can sustain and vice versa. Most modern gearboxes use a GL-4 oil while separate differentials require a GL-5 oil as it contains more EP additives that lower the coefficient of friction.
Royal Purple Gear Oil, Max Gear is carefully engineered for use in truck, motor home/RV, and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. The high quality synthetic oil is further fortified with Royal Purple's proprietary Synslide additive technology that makes it outperform other GL-5 synthetic oils in terms of lower friction, decreased operating temperature, excellent corrosion protection, maximum horsepower, suppressed oil-water emulsion and prolonged gear and bearing life.
