What oil goes in a rear differential?
There are two types of differential fluid. One is mineral oil, which is a natural, crude oil-based fluid. The other is synthetic differential fluid, which is created in a lab.
What differential fluid 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.

Is gear oil the same as differential fluid?
Every front or rear axle is filled with a special oil (also called differential fluid, or gear oil) that takes care of this. The differential fluid lubricates the gears, bearings and other internal parts, and provides cooling to these components as well.
What’s better 75W90 or 75W140?
A 75W-90 will be thinner at higher oil temperatures than a 75W-140. Both are the same thickness at lower oil temperatures. The 75W-140 is said to have a wider viscosity range – when more accurately it would be a wider temperature range.
Which is better 75W90 or 80W90?
Ans: 75W90 is artificial and mostly better than 80W90, but it costs more. 75W90 has a better low-temperature viscosity and is good to run all over. If you’re in a warmer zone, using 75w90 will be more suitable than 80w90 for you.
Can you add too much limited slip additive?
If you add too much limited slip additive, you’ll notice your wheels will break loose super easy and you’ll get wheel-spin just making turns from a stop. If you make that mistake (like I did), just drain the oil and refill and you’ll be good.
How long does differential oil last?
The oil needs to be changed every 30,000 to 50,000 miles, unless your owner’s manual states otherwise. The differential is a part in your vehicle that compensates for the difference the inner wheel and the outer wheels travel when you turn a corner.
