GEAR OILS

Gear oil is the broad term for several different types of lubricants and fluids that support the functioning and performance of the gear systems within a vehicle. Similar to engine oil (although not the same), it serves multiple purposes, from protecting gears from wear and tear to dissipating heat and reducing friction. At Conlan Oils we aim to provide you with the very best gear oil for your requirements. We provide Gear Oil in the specifications below.

Specifications Available:

75w/80 , 75w/85, 75w/90, 75w/140, 80w/90, 85w/140

EP 80, EP 90, EP 100, EP 150, EP 220, EP 460, EP 680

GEAR OILS EXPLAINED

Gear oil is the broad term for several different types of lubricants and fluids that support the functioning and performance of the gear systems within a vehicle. Similar to engine oil (although not the same), it serves multiple purposes, from protecting gears from wear and tear to dissipating heat and reducing friction.

An essential ingredient to the smooth running of your car, truck, bus or machinery here we’ll go over three things you need to know about gear oil, and cover some FAQs about this crucial lubricant.

1. There are different types of Gear oil

Gear oil is a vague term that could refer to multiple fluids used in various vehicle types. Most commonly, gear oil refers to manual transmission fluid (MTF), a lubricant that reduces friction inside a manual gear system.

On the other hand, automatic transmission fluid (ATF) is used in automatic transmissions where gear shifts happen without manual intervention, supporting the transfer of power from the transmission to the engine. It has slightly different properties to MTF because it operates under less heat and pressure.

Other types of lubricants include differential gear oil and transfer case fluid.

Every vehicle has a differential that allows the wheels to rotate at different speeds when turning. Differential gear oil is a lubricant used to lubricate the gears and bearings inside this differential. Its unique additive formulation helps reduce wear and tear on these components that experience high pressures and shock loads during acceleration, braking, and cornering.

In four-wheel drive vehicles, there is also a transfer case that directs power from the transmission to all four wheels. Transfer case fluid lubricates the gears and bearings inside this transfer case. While not under the same extreme conditions as the differential, the transfer case fluid still contains protective additives to ensure proper lubrication and prevent premature wear.

Using the correct differential and transfer case fluids recommended by the manufacturer is important for the long-lasting performance of these drivetrain components.

2. Viscosity is important

Different types of gear oil have different viscosity (thickness) grades. Gear oil viscosity is usually graded by two numbers separated by a ‘W’, such as 75W-90. The ‘W’ stands for winter, so the first number indicates the oil’s viscosity or property at a cold temperature. The second number indicates the oil’s viscosity/property at higher temperature.

The higher the numbers, the greater the viscosity (thickness) of the oil. Thicker gear oils are typically used for higher heat and high-pressure applications, and mostly in manual transmission vehicles.

Automatic transmission fluid tends to be much less viscous because it needs to flow freely for smooth transmission of power from the engine to the wheels.

3. Synthetic vs. conventional Gear oil

Synthetic gear oil is gaining popularity as a high-performance alternative to traditional petroleum-based lubricants. Synthetic gear oil can typically handle higher temperatures and can be fine-tuned at a more molecular level to enhance specific performance metrics.

With synthetic, viscosity remains more of a constant as temperature changes, making it more reliable in fluctuating conditions. Finally, synthetic gear oil tends to form a stronger film to protect internal components, which lasts longer than its traditional mineral counterpart.

Having said all of this, quality mineral gear oil from a trusted brand will still offer a range of benefits to help you shift gears smoothly.

GEAR OIL – Frequently Asked Questions

What is Gear Oil?

Gears are found in a vast amount of the machinery we see today and are essential components as they perform several key functions including, gear reduction and adjusting the direction of rotation. But if a gear didn’t have a lubricant, it wouldn’t be able to perform these key functions. Whether in your car, truck or heavy industrial machinery, these lubricants allow gears to slide along smoothly by stopping friction from wearing them down.
