Can I use 80W 90 instead of 75W90?

Ans: Yes, you can mix 75w90 with 80w90.

What is the difference between 75W90 and 80W90 gear oil?

SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.

What is 80W90 gear oil used for?

Application. Gear Oil 80W-90 is designed for use in differentials, both hypoid and limited slip, manual gearboxes, transfer cases and transaxles in passenger cars, light commercials, 4WDs, trucks, construction, earthmoving and agricultural equipment, where this viscosity grade is required.

Can you use 80 90 gear oil?

80W-90. The 80W-90 gear oil can be used in extreme pressure conditions and as a lubricant for non-synchronized manual transmissions in heavy duty trucks or buses. This gear oil is recommended for conventional and limited slip differentials.

Can I use 80w90 instead of SAE 80?

Yes it is the same… close enough anyway. SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want.

Can I use SAE 90 instead of 80w90?

Can I use regular gear oil in my lower unit?

So, can you use any old gear lube in your marine lower unit? If you want the best protection possible, and want your lower unit to last as long as your boat, then the answer is no. Consult your engine’s manual and look for the proper marine gear lube for your application.

Is 80W 90 same as 80W?

It just thins less than a straight 80w would, ending up as thick as a 90w would be when warm. Unless there’s some unusual reason your ATV must have straight weight, 70w-80 would be the way to go. Then it will be the proper viscosity when warm.

Is 80W the same as 10W 40?

The most common mistake is the belief that the viscosity of SAE 80W gear oil is much thicker than the viscosity of SAE 10W-40 motor oil. This is absolutely incorrect! A 10W-40 motor oil’s viscosity is actually similar to the viscosity of 80W gear oil, and the viscosity of SAE 10W-30 is similar to 75W gear oil.

What is the difference between 75 90 and 75W-140 gear oil?

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.
