Most individuals assume that when it's time to get their oil changed, it's their engine oil that needs to be changed. While this is the most common lubricant that requires regular care from car owners, it is important to remember that there are other parts of your automobile that require good lubrication as well. However, it is also important for them to keep in mind that they only opt for the top quality gear oil.

Now, there are several disagreements over rear end gear oil between new and old car owners, as well as between generations of automobile owners. Some manual transmission owners insist on using a high viscosity oil, while others are content with ATF. Some owners only use synthetic or natural oils, and there's always the debate about whether to change the oil in a gearbox.

In this blog, we will help you to understand the basics of when and why you should change gear oil.

What is the purpose of gear oil?

Gear oil lubricates the transmissions, differentials, manual gearboxes, transaxles, and transfer cases in your automobile or truck. The smooth running of your gearbox is aided by rear end gear oil. More importantly, it aids in the protection of essential internal gear system components from wear and heat damage.

Important drivetrain components might be scoured, corroded, scuffed, and pitted as a result of insufficient lubrication. This deterioration might affect your car's performance and lead to expensive repairs. There is a difference between gear oil and engine oil, and they are not interchangeable. Gear oil is designed specifically for use on gears. When choosing the right gear oil for your vehicle, you need to make sure that you only go for the top quality gear oils.

When to change your gear oil?

When it comes to changing your gear oil, the truth is that there is no fixed guideline. It all relies on your driving circumstances as well as the typical temperature of your vehicle. High-stress driving raises the temperature of your transmission, eventually causing the gear oil in your automobile to lose its stability. If you tow frequently, drive in low-traction circumstances, or go through mountainous terrain, you'll probably need to change your gear oil every 30,000 miles, or perhaps sooner. It is always advisable to go for the top quality gear oil for optimum performance.

Most cars can travel up to 80,000 miles in normal driving conditions before requiring arear end gear oil change. This is a maximum number, and most manufacturers recommend replacing your gear oil every 50,000 to 60,000 miles.

Other issues that necessitate a gear oil change can arise under exceptional circumstances. Your gear oil should be changed if your transfer case, differential component, or transmission has been submerged in water or any foreign fluid. With insufficient lubrication, contaminated oil can badly harm your gearbox, transfer case, or differentials. Top quality gear oil ensures superior performance.

If your transfer case or differentials just had a leak repaired, you should also change your gear oil. A leak could indicate contamination or low gear oil levels. After repairing a leaky component, most experts will replenish your gear oil, but this is commonly overlooked with amateur repairs.

How often should you change the gear oil?

If you use your automobile for towing or driving in muddy or otherwise difficult conditions, you should change your gear oil every 30,000 to 50,000 miles. Some car manufacturers recommend changing gear oil every 60,000-80,000 miles under typical driving circumstances, while others advocate examining the gear oil at regular service intervals and replacing it if it becomes unclean.

Ford goes even farther, claiming that synthetic gear oil in rear axles and power take off (PTO) units (transfer cases) is lubricated for life in some models under typical driving conditions. Naturally, every mechanical system will wear down over time, and changing gear oil is significantly less expensive than replacing a transfer case or rear differential. Many experts recommend replacing the rear end gear oil every 60,000-70,000 miles or sooner.

Mineral gear oil needs to be changed more frequently, whilst synthetic gear oil lasts longer. The fill and drain plugs are located in the rear differential. If the component (transmission, transfer case, or differential) has been submerged in water, the gear oil must be changed immediately.
