80w90 Gear oil

When you think of heavy-duty vehicles, the first thing that pops your mind is trucks, buses, and vans. Demonstrating quality as oil in such heavy-duty vehicles is never an easy task. Still, this oil has stood up to the challenge. Not only do the oils have to lubricate the vehicles’ parts but also it has to prove their worth in reducing water contamination.

The stability of the oil is a critical observation. The temperature will constantly vary with thermal and operative conditions, and so far, this product has consistently met the needs. The oil comes with an ideal viscosity, which may make you think this is an easy task. Actually, it’s not. The engineering team has put a lot of effort into creating the fully synthetic formula out of base oils. We now take a look at their main features and benefits that make this oil stand out in the crowd.

  • Exceeds the GL-5 and MT-1 requirements
  • Operable under extreme conditions like low-torque, high shock load.
  • Top-of-the-range thermal stability that enhances your gear life.
  • Good protection all over so there is no need for repetitive workshop travel.
  • Sturdy seal to eradicate leakage and ultimately eradicate contamination
  • Suitable viscosity ensures equal lubrication in all parts and quality formula to resist any foaming.

What is 80w90 gear oil used for?

Gear oils are mainly used in transmission, both manual and automatic. The prime reason is to lubricate them for better gear shifting. Though it is used for this reason, it is not the sole purpose of the oil. This oil helps reduce corrosion, and the fluidity eliminates oxidation, so you can stop worrying about the gears.

What does 80w90 mean?

The numbers are universally accepted as an oil grading system. In the middle, we have a ‘W,’ which denotes winter. The myth that the W means the weight is not accurate at all. The numbers on both sides of W are the viscosity the gear oil will offer in different temperatures.

The first number 80 states that the oil is destined to work well at low temperatures. And the second number, which in this case is 90, signifies the oil’s thinness at 100 degrees Celsius.

Which gear oil is thicker 80w 90 or 85w 140?

Looking at the names, the idea is pretty clear that the later one is thicker in both room and application temperatures. The first one here is quite thick to be accurate, but the 2nd one wins this round very quickly. The thickness of oils is measured from 10 to 140. So, it’s apparent that the second one is thicker.

What is the viscosity of 80w90?

This oil is a balanced product that has been used for quite some time. It has a viscosity index of 110. Viscosity changes with the temperature. It offers a kinematic viscosity of 15 when the temperature is 100ºC and 139 when it is 40ºC. Pour points and flash points are -27ºC and 218ºC, respectively.

Our observation

As we learn the specification of the oils, we see that they are both equally suitable for heavy usage with a chunk of reliability. First oil here is more widely used and bought by users who intend to use it for vehicles that are not much into towing or heavy stuff. But the later one is chosen and dedicated towards heavy usages like trucks, vans, and buses. Here’s a similar comparison you might be interested in 5w40 vs 10w30.

Conclusion

From the above, we can see that both 80w90 and 85w140 gear oils have their own set of benefits and drawbacks. However, if we had to choose one, we would go with 85w140 gear oil as it is thicker and thus offers better protection for the gears. I hope this article, 80w90 vs 85w140 gear oil, has helped you make a more informed decision when it comes to choosing the right gear oil for your car.
