To get rid of such issues, we are here with two different gear oils which can prevent gear’s wear or scuffing and handle heavier loads in severe conditions.
Want more clarification about 75w90 vs 75w140 gear oil? Scroll through our detailed guide for a quick answer and pick the best one to get extreme gear protection with durability.
75w90 Gear Oil: Thicker Viscosity With Better Fuel Economy
On the top, we start the journey with the 75w90 Gear Oil, which is in demand here due to its thicker viscosity at low temperatures, better fuel economy, extreme pressure additives, outstanding thermal stability, and the highest level of performance. Let’s dig into these specs of the gear oil in detail.
While driving through extremely cold weather, gear oil with thin viscosity can’t handle heavier loads during hauling operations. But, the Valvoline 75w90 Gear Oil offers a thicker viscosity at low temperatures. As a result, it can handle heavier loads even at extremely low temperatures.
In addition, these gear oils adopt a premium formulation that offers excellent low-temperature fluid protection for a longer time. That’s why the 75w90 gear oil won’t lose its viscidity rapidly and will keep the performance curve straight for hours while dealing with cold weather. Also, the thicker viscosity of the oil helps in quick acceleration and improving braking results.
Along with that, the 75w90 gear oil comes with a thinner viscosity grade for high-temperature regions. This viscosity grade can increase fuel affectivity, resulting in better fuel economy than other grades. In fact, fuel usage is quite noticeable if you’re a daily driver who spends hours on the road.
However, these synthetic gear oil adopts a pressure formula that includes premium additive packages. With such an additive formulation, the 75w90 gear oil can minimize gear wear from any shock load. In short, the thermal stability of the gear oil protects the oil from temperature breakdown and ensures better activity on the road.
Besides, the formula can offer protection against scuffing, scouring, or corrosion to prolong the gear’s life. Further, the outstanding performance in severe driving conditions makes the gear oil perfect for passenger vehicles in city traffic.
The only issue with the 75w90 gear oil, it quickly loses viscosity in hot temperatures. But, all in all, these are the perfect gear oil for enjoying heavy performance even at extremely low temperatures.

The 75w90 gear oil has a thicker viscosity at low temperatures, which handles heavier loads even in extremely cold weather. If you’re living in a cold temperature region and looking for top-notch gear performance, we suggest you pick the 75w90 gear oil right now!
75w140 Gear Oil: Excellent Fluid Protection With Thermal Stability
On the other hand, we have the 75w140 Gear Oil, which is well-known for its excellent low & high-temperature fluid protection, outstanding thermal stability, special custom additives, and superior performance. Let’s have a look into these specs of the gear oil in detail.
Most of the gear oil loses viscosity when you’re on the road in hot weather. Due to such quick loss, these oils impact durability and can’t handle the changes in temperature. The Valvoline 75w140 Gear Oil now has a thicker viscosity at high temperatures. As a result, these oils can handle the engine’s high temperatures and enhance the gear parts’ durability.
In fact, the 75w140 gear oil offers a thicker viscosity at low temperatures, which results in handling heavier loads even at low temperatures. Besides, the gear oil’s outstanding thermal stability helps maintain the engine oil’s cleanliness. As a result, these gear oils can last longer than the service life of the gear parts.
On top of that, these 75w140 gear oils include the latest formula, which contains high-quality additive packages. These additives minimize gear wear from any shock load. Hence, these oils can perform better in severe driving conditions. Also, the combo of custom additives can ensure optimum wear protection and keep the performance top-notch for longer.
Moreover, these gear oil comes with superior shear stability with oxidation control. Due to such controlled stability, these oils can resist mechanical stress from different forces and offer better performance on the road. Hence,75w140 gear oils protect the moving engine parts from wearing while dealing with higher loads.
The only drawback of the gear oil is that its viscosity grade is less fuel efficient, resulting in higher fuel consumption. Keeping minor issues aside, these gear oil can offer superior performance in any temperature condition.
