A unique and stiff oil to protect the gears. It performs best in heavy duty vehicles.

Built with superior materials and a first choice of many regular vehicle users.

80w90 Gear oil

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

The stability in an oil is a critical observation. With thermal and operative conditions, the temperature will constantly vary and so far, this product has always met the needs. The oil comes with an ideal viscosity and that may make you think that this is an easy task. Actually, it’s not. The engineering team has put a lot of effort to create 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 eradicating contamination
  • Good viscosity to ensure equal lubrication in all parts and quality formula to resist any kind of foaming.

Our observation

As we learn the specification of the oils, we see that they are both equally good 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 usage like trucks, vans and buses. Here’s a similar comparison you might be interested in 5w40 vs 10w30.

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 out 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 the word winter. A myth that the W means weight, is not true at all. The numbers on the both sides of W are the viscosity the gear oil will offer in different temperatures.

The first number 80 is a statement that the oil is destined to work well at low temperatures. And the second number, which in this case is 90 means signifies the thinness of the oil at 100 degree 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 temp and application temp. The first one here is quite thick to be true but the 2nd one wins this round very easily. Thickness of oils are measured from 10 to 140. So, it’s very clear that the second one is thicker.

What is the viscosity of 80w90?

This oil is a very balanced product that has been in use 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 temp is 100ºC and 139 when the temp is 40ºC. Pour points and flash points are -27ºC and 218ºC respectively.
