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.
What is the difference between 85W90 and 80W90?
85W90 is only flowable down to -12 °C, 80W90 on the other hand down to -26 °C. If your vehicle is regularly exposed to very cold temperatures, we recommend 80W90 transmission oil, otherwise 85W90 can also be filled in. The performance parameters of the oils of both SAE classes are identical in many respects.
What is EP 80W90?
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.
What viscosity is 85w140?
Typical Properties
| Mobilube HD LS 80W-90 | 80W-90 | 85W-140 |
|---|---|---|
| Viscosity, ASTM D 445 | ||
| cSt @ 40ºC | 136 | 328 |
| cSt @ 100ºC | 14.5 | 25.3 |

Is 85W140 synthetic?
Twin Power Semi Synthetic 85W140 provides smooth shifting. Our semi-synthetic base formula means ultra-high films strength and shear stability that resists viscosity breakdown and increases service life.
Can you mix synthetic and regular gear oil?
So, in the end, conventional and synthetic oils are comprised of the same, compatible components – it’s just that the components in synthetics are much higher quality. While you can safely mix synthetic and conventional oils, you’re doing nothing more than diluting the performance of the synthetic oil.
What does EP mean for gear oil?
extreme pressure
In a boundary condition there is no separation of the interacting surfaces. The function of an extreme pressure (EP) additive is to prevent this adhesive wear and protect the components when the lubricating oil viscosity can no longer provide the necessary film thickness.
What does EP 90 mean?
Classic Gear EP 90 is a mineral SAE 90 transmission oil. The product is suitable for use in manual transmissions and other transmissions in classic vehicles that require a medium single-grade oil with extreme pressure protection that meets the API GL-4 specification.
What is the viscosity of gear oil?
SAE 75W-140
| Temp. [°C] | Dyn. Viscosity [mPa.s] | Density [g/cm³] |
|---|---|---|
| 10 | 768.20 | 0.8592 |
| 20 | 410.55 | 0.8529 |
| 30 | 236.53 | 0.8466 |
| 40 | 145.40 | 0.8404 |
What is the viscosity of 85W-140?
What is SAE 85W-140?
The first number of the designation specify the oil viscosity at cold temperature, the second number specifies the oil viscosity at high temperature. For example: SAE 85W-140 oil has a low temperature viscosity similar to that of SAE 85W, but it has a high temperature viscosity similar to that of SAE 140.
What is the difference between 80w90 and 85w140?
Hot 80W90 is the same as hot SAE90. Cold 85W140 is the same as cold SAE85. Hot 85W140 is the same as hot SAE140. Short answer: 85W140 is thicker.
What does 80W 90 mean on gear oil?
In the case of 80w 90, the first number “80” means the gear oil will work good in lower temperatures. Then the number “90” refers to the viscosity of this gear oil at 100° C or higher temperatures. The description is the same for 85w 140.
What is 85w140 gear oil?
In brief, the 85w140 gear oil is a high-performance, strong gear oil. They are exclusively made from general base oils, which helps their effectiveness a lot. These gear oils can provide you a smooth and healthy service when it comes to heavier, more power-absorbing vehicles.
What is the difference between sae140 and hot 85w140?
Hot 85W140 is the same as hot SAE140. Short answer: 85W140 is thicker. Long answer (I realize this part will likely be confusing): Oil viscosity is temperature dependant, with the first number on a multigrade oil saying how thick it is when cold, and the second number when hot.
