What is 80w90 gear oil?
Lubricant. 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.
What is the viscosity of 80W-90 gear oil?

Which grade oil is used in gearbox?
For example, most modern gearboxes require a GL-4 oil, and separate differentials (where fitted) require a GL-5 oil. While they take the same form, the viscosity grades for gear oils are on a different scale than the viscosity grades for an engine oil.
What is 140W gear oil?
Hypoid Gear Oil (GL5) SAE 140W is a high-performance, high-pressure gear oil manufactured from carefully selected base oils and multifunctional extreme pressure additives. This hypoid gear oil is suitable for axle drives – especially for heavy-duty hypoid transmissions.
What is the difference between hypoid and regular gear oil?
Hypoid Oil Differences It’s a gearbox oil, just like others, but the ingredients are different. This type of gear oil is mixed with additives designed to increase its resistance to breakdown under high temperature and mechanical pressure produced by hypoid gearboxes.
Can I put gear oil in my automatic transmission?
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.
What does 80W mean?
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.
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!
How do I choose the right gearbox oil?
How do you select a gearbox oil?
- Gearbox type: dimensions, the metal from which the teeth are made, sliding properties and gear ratio, open or closed casing, etc.
- Operating conditions: depending on the load, vibration and shock levels, anti-wear and extreme pressure properties determine the choice of lubricant.
What is the viscosity of 90 weight gear oil?
| Gear oil SAE 80W-90 | ||
|---|---|---|
| Mineral based multigrade gear oil | ||
| Kinematic viscosity at 104°F (40°C) | 139 | 139 |

What is 90w gear oil?
What is 90 weight gear oil used for? The 75W-90 gear oil is used under extreme pressure conditions and is recommended for limited-slip differentials and for use in colder climates. Used in heavy duty manual transmissions, final drives and axles, high temperatures will not effect the heavy film left by this oil.
