GEAR OILS: How to Direct Longer Your Vehicles and Machines.

Updated: Apr 14, 2023

Gear Oils are as important as engine oils, representing 20% of the lubricant market. But even with this representation, some doubts can come about the specific uses and benefits of such lubricants. In this article, we will try to go through everything you need to know regarding these particular lubricants. Gear oil is a lubricant formulated for gears, gearboxes, and transmissions requiring high-viscosity grades and it is used in trucks, Heavy-duty equipment, transmissions, agriculture vehicles, etc. It makes the transmission smooth and protects internal components from damage. Gear oils range is composed of full-synthetic, semi-synthetic, and mineral-based Oils. And together with special formulas of highly engineered and innovative additives, it provides efficient operation and protection to gears, transmissions, and differentials automotive components under light, medium, and heavy loads. There are a lot of types of gear oils in the market but before choosing the right oil type check the manual of your vehicle. The wrong choice of lubricant can have the opposite effect ( low performance, damage to components) and harm your vehicle and machine gearbox and components. One possible thing to do is to check in the product list from your manual maintenance the qualified product list ( QPL) to have a better idea of which one you could choose. Also, some criteria should be considered such as viscosity, the additives ( this will define the general category of the lubricant) working conditions of the machine, etc. The gear oil designations are set by the American Petroleum Institute (API) for passenger vehicles and can be: API GL-4: Passenger car and light truck manual transmission lubricants, oils used in tractor gearboxes, and spiral bevel gear final drives. API GL-5: Passenger cars, light heavy trucks, and buses (hypoid final drives) where there is a large amount of sliding movement across the gears. In terms of viscosity, you can find 75W-90, 80W-90, Monograde Gear Oil, and Multigrade Gear Oil. Considering the following: 75W-90 gear oil is proper under extreme pressure conditions and recommended for limited-slip differentials and for use in colder climates; 80W-90 gear oil proper to be used in extreme pressure conditions and as a lubricant for some non-synchronized manual transmissions in heavy-duty trucks or buses; SAE defines the gear oils suitable for operation at one temperature on a monograde scale. Meant for high ambient temperatures is made by a number;

Multigrade gear oils have additives that change their viscosity at different operating temperatures. The right moment to change your gear can depend first on what the owner’s manual indicates, but the smoothness of the transmission when shifting the gears is crucial. The problem is when you change the gear oil if there is any type of burning smell in the car, etc. it can signal that you should check or change your gear. Some automotive manufacturers ask that the lubricants follow their own in-house specifications. Mercedes-Benz, GM, Scania, Ford, Volvo, and others have some requirements for gear lubricants to be applied in their automobiles. As you can conclude, quality lubrication can prevent corrosion, scuffing, and other damage in your vehicle and machine that can compromise the performance and future costs of repair.
