Is 80W-90 the same as 10W 40?

Is 80W-90 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!

What can I use instead of 90w gear oil?

SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want. 15W40 diesel oil is close enough to dump in there.

What is Ep 80 90w gear oil?

EP 80W-90 Gear Oil is a mineral oil based lubricant formulated for use in a wide range of automotive, plant, agricultural and industrial transmission systems. This grade has a high level of extreme pressure (EP) additive that provides effective gear protection over a range of temperatures and shock load conditions.

Can I use 85W140 instead of 80W90?

Hot 80W90 is the same as hot SAE90. Cold 85W140 is the same as cold SAE85. Hot 85W140 is the same as hot SAE140. Now moving to only monogrades (to simplify, this still applies to multigrade oils, I’m just leaving that part out so it’s less to take in at a time).

What is 80W 90 oil?

The numbers “80W-90” refer to the viscosity grades of the oil. Since it has two numbers, this oil has two viscosity grades. The ‘W’ means winter. The number “80” — in this case — signifies that the oil is designed to work well in lower temperatures. The lower the number, the thinner the oil must be.

What oil is equivalent to sae90?

Because the viscosity of gearbox and engine oils are measured on different scales, an SAE 80 gearbox oil is roughly equivalent in viscosity to an SAE 20 engine oil. An SAE 90 gearbox oil is roughly the same viscosity as an SAE 50 engine oil. Most manufacturers now offer EP80W/90 oils in place of both EP80 and EP90.

Can I use SAE 90 instead of 75w85?

Very close viscosity. Most diffs were designed with 75W-90 in mind. Going to 75W-85 was a fuel-economy-boosting endeavor. AMSOIL Severe Gear 75W-90 is designed to replace, 75W-90, 75W-85, 80W-90, SAE 80 or SAE 90 gear oils. It can replace any of these with no worries or risk.

Can 75W-90 replace 80W 90?

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

Is 75W-90 the same as 80W 90?

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’s the difference between 80W 90 and 85W-140?

The viscosity chart rates the 80W90 up to 95 degrees while the 85W140 is rated up to 120 degrees.

What is 85W140 gear oil used for?

Gear Oil GL-5 SAE 85W-140 gear lubricant is recommended for use in spiral bevel and hypoid differentials, power dividers, and oil-lubricated steering axle wheel bearings. Good gear life — Extreme pressure properties protect hypoid and other types of gears from scuffing and wear.
