Is Differential Oil The Same As Gear Oil?

Can I use 80w 90 instead of 75w90?

If you have differential whine that is quieted by a thicker fluid, then 80W-90 might be a good option.

It will certainly be thicker than 75W-90 for most owners’ operating conditions in moderate climates.

You could also try 75W-110 for a thicker oil that performs better in the winter..

Can I use SAE 90 instead of 75w90?

Yes. 75w-90 should be just fine.

Is Thicker gear oil better?

When it comes to lubricants, especially for axles, the stance among fleet owners and operators has traditionally been that thicker viscosity is better. After all, thick lubricants do protect. Gear oil must protect critical hardware within the axle while operating in extremely demanding conditions.

Can I put gear oil in my transmission?

What does this mean for my vehicle? Whilst some manual gearboxes do use transmission fluids in place of gear oil, the same cannot be said for putting gear oil into an automatic transmission. Gear oil is much too viscous for these systems and will cause clogging between components.

Can you use 75w140 instead of 75w90?

I think you’ve got your numbers backwards the 75W140 is the heavier (140 vs 90) and for more severe service. It is recommended only for the rear diff and only for heavy towing and continuous use. You shouldn’t go heavier than 75W90 in the front and for normal duty and occasional towing 75W90 is fine for the rear.

What is 80w90 gear oil used for?

The oil known as 80W-90 GL-5 is a lubricant for the gears in your vehicle. It is used in automatic and manual transmissions, and assists the gears in shifting smoothly.

Can I use gear oil in a hydraulic jack?

Yup. “hydraulic jack oil”. But ATF, p/s fluid, motor oil, or any ol’ hydraulic oil will also work in a pinch- nothing will come of it.

What’s thicker 75w90 or 75w140?

So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.

What is the difference between gear oil and hydraulic oil?

Hydraulic fluids are normally a 10 to 30 weight and Gear oil is a 80 weight or higher. The different uses and requirements come from pumps,seals and use. The design of the total system.

Can you put motor oil in a differential?

Transmissions do not have quite the same high pressure stresses that differentials do. Motor oils have to deal with shearing a lot more than pressure, so there’s a whole different set of design parameters. No way should you put motor oil in your differential.

Can I use 80w90 instead of SAE 90?

Re: Does SAE 90 = 80W90? 80W90 means the oil flows like a 80 weight oil cold, yet lubricates like a 90 weight oil when hot as defined by the SAE test procedure. Use it when SAE 90 is specified.
