What is the difference between 80W90 and 85W140 gear oil?

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

What is the thickest gear oil?

The SAE grading system indicates oil viscosity in simple numbers ranging from the thin oil (10) to the very thick oil (140 or above). Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears. Light grade oil is ideal for small, fast, polished gears under a light load.

What is 85W140 gear oil used for?

Application. Gear Oil 85W-140 is designed for use in differentials, both hypoid and limited slip, in passenger cars, light commercials, 4WDs as well as in on- and off- highway truck, construction and agricultural equipment where such a viscosity grade is required.

What is 85W 140 gear oil?

Mobilube™ HD Plus Gear Oil 85W-140 is an extra-high-performance commercial gear oil formulated from select base oils and an advanced additive system. This oil is engineered for performance in heavy-duty commercial transmissions, axles and final drives where extreme pressures and shock loading are expected.

When should I use 140 gear oil?

Recommended by ExxonMobil for use in: Off highway industries including: construction, mining, quarrying, and agriculture. Other heavy duty industrial and automotive applications involving hypoid gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque prevail.

What is 80W 90 gear oil for?

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.

Is 80W 90 the same as 90 weight gear oil?

It’s important to know the difference between 75W90 and 80w90 gear oil because they’re not interchangeable. For example, if you were going to use 80w90 gear oil on an axle operating at high temperature (over 212 degrees Fahrenheit), the fluid would be too thin and could cause the axle to wear out prematurely.

What is thicker than 80w90?

Which gear oil is thicker, 80W 90 or 85W 140? – Quora. Short answer: 85W140 is thicker.

Is 85W-140 synthetic?

Lucas 85w140 Non-Synthetic Gear Oil – Quart.

What is 80W-90 gear oil for?

Is 85W-140 gear oil Synthetic?

Royal Purple Max Gear 85W-140 Full Synthetic Gear Oil.

What does 80W 140 mean?

The 80W90 and 80W140 are high performance SEMI-SYNTHETIC GEAR OILS with ANTI- FRICTION TREATMENT. They provide superior lubricity which means less wear caused by friction and improved gear protection at extreme temperatures.
