What is the Differential/Gear Oil all about?

Differential oil can be described as a type of oil. The gearbox connects the two axles of a car. This is the part of the car that converts engine power to its transmission and allows them to turn at different speeds. 

The differential is an important part of the car and requires lubrication to work properly. The car’s differential is cooled and lubricated by differential fluid (also known as differential oil). This fluid protects the metal surfaces of the gears from friction and prevents overheating and burning.

Remember:

  • Some vehicles have front differentials, while others have rear differentials.
  • Some vehicles use synthetic gear oils.

How it is done:

  • Check fluid level.
  • Check the rear housing for any leaks.
  • If the differential doesn’t have a drain plug, remove the cover.
  • If necessary, replace the gasket.
  • Replace with new fluid

Our recommendation:

You should change your differential oil every 30,000-50,000 miles. It is a good idea for the gear oil to be changed at least once every 30,000 miles. However, it is a good idea to have a mechanic inspect the differential oil as part of regular maintenance.

What type of gear oil for the F350 rear axle?

But if your F-350 has dual rear wheels, it has a Dana 80 rear axle that requires SAE 75W-90 Synthetic Gear Lubricant XY-75W90-GLS. Ford told their techs to use 75w140 synthetic for deals that work hard. The front axle requires SAE 90 Premium Rear Axle Lubricant C2AZ-19580-F per the workshop manual, but your Owner’s Guide probably says 75w90.

Type: It depends on the year. The truck came with Gold or Green Coolant. See your manual for SCA requirements!!

Do Differential Oils need to be replaced?

However, automotive mechanicals almost completely relies on liquid lubricants, or simply oils. The differential is a set of gears transmitting a tremendous amount of energy and requires lubrication as well. Unlike engine oil, the liquid inside the differential cover doesn’t need to be changed or refilled often.

What differential oil do I need?

Use the highest-quality gear oil you can afford to fill the differential. The weight and capacity will be listed in your owner’s manual; your differential will usually hold as much as 3 quarts. Be sure to read that manual, though, because some limited-slip differentials require a secondary friction-modifying additive
