FAQ 1998 e320 front diff oil type

What kind of oil do you put in a rear differential?

For this job, we are using Redline 75/90W Synthetic High-Performance Gear Oil. You’ll need 1.5 quarts to fill the differential. First, drive the car around the block a few times to get the oil inside the differential warmed up. The fluid will flow out of the differential easier when it is warm.

What happens if you don’t change the differential oil?

Also, the differential uses oil that is much thicker than engine oil. Usually, differential oil is good for up to 80,000 miles without changing. However it is commonly overlooked in the wide spectrum of vehicle maintenance. Failure to change the fluid at regular intervals can eventually cause the bearings in the differential to fail.

How much oil does it take to fill up a differential?

You’ll need 1.5 quarts to fill the differential. First, drive the car around the block a few times to get the oil inside the differential warmed up. The fluid will flow out of the differential easier when it is warm.

How do you drain the oil from the rear differential?

Put a drain pan of at least 2 quarts capacity under the plugs and first open the top plug to relieve any possible vacuum inside the differential and help the oil drain out. Now loosen the lower plug and thread it out by hand.
