What oil goes in the 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 is the best oil for differential?
Red Line MT-90 — Best Differential Fluid.
Is all differential oil the same?
All gear lubricants are definitely not the same. There are differences in the additive technology used for lubricants for each specification, and just because one type of gear oil works well for one type of gear application, that doesn’t mean it will work well for all.
How do I put gear oil in my rear differential?
- Step 1: Secure the vehicle on jack stands or ramps.
- Step 2: Allow time for the gear oil to completely drain.
- Step 3: Locate and remove the gear oil fill bolt.
- Step 4: Use a pump to slowly add the recommended type of gear oil to the differential.
Can I use 75w140 instead of 75w90?
Can I use 75w140 instead of 80w90? Either one is fine. Generally the synthetic 75w-140 is for HD applications such as towing, but it will work fine in any application.
What’s thicker 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.
What happens if you don’t change differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
How much gear oil goes in a differential?
Fill to the Brim 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.
What’s better 75W90 or 75W140?

What should I put in my Dodge Ram differential?
If the differential is LSD, pour the 4 oz. of limited slip additive into the filler spout first. Then add the gear and axle lubricant. Figure 16. Pour limited slip additive into the differential. Figure 17. Pour gear and axle lubricant into the differential. When the fluid starts running out of the filler spout (about 72 oz in this case), stop.
What kind of oil do you use for a limited slip differential?
AMSOIL gear oils are formulated with friction modifiers for limited slip differential applications. There is no need to add limited slip or additional additives. -After changing the differential fluid, drive the vehicle in 7 or 8 figure eight turns, so the new lubricant can work its way into the axle assembly.
