What kind of differential fluid does a 2017 Ram 3500 take?
The 2017 Ram 3500 heavy-duty pickup truck requires a specific type of differential fluid to ensure proper operation and lubrication of its rear differential. According to the manufacturer's recommendations, the 2017 Ram 3500 should use a SAE 75W-90 synthetic gear oil or a SAE 80W-90 conventional gear oil in its rear differential.
Rear Differential Fluid Specifications for the 2017 Ram 3500
The rear differential in the 2017 Ram 3500 is a critical component that transfers power from the transmission to the rear wheels. To keep this differential functioning properly, it requires the right type of lubricating fluid. The manufacturer specifies the following requirements for the rear differential fluid:
- Fluid Type: SAE 75W-90 synthetic gear oil or SAE 80W-90 conventional gear oil
- Fluid Capacity: Approximately 3.5 pints (1.65 liters)
- Fluid Change Interval: Every 30,000 miles (48,000 km) or 24 months, whichever comes first
Using the correct differential fluid is important to prevent wear, reduce friction, and maintain the proper operating temperature of the rear differential. Failure to use the recommended fluid can lead to premature component failure and costly repairs.
Why the Specific Fluid Recommendation?
The 2017 Ram 3500's rear differential is designed to work best with a SAE 75W-90 synthetic gear oil or a SAE 80W-90 conventional gear oil. These fluid specifications provide the necessary lubrication, viscosity, and extreme pressure (EP) properties to handle the high loads and torque demands of the heavy-duty truck's rear axle. Synthetic oils generally offer improved performance and longer service life compared to conventional gear oils.
It's important to follow the manufacturer's recommendations for the rear differential fluid to maintain the warranty and ensure the long-term reliability of the 2017 Ram 3500's drivetrain components.
What fluid should I put in my rear differential?
There are two types of differential fluid: mineral oil and synthetic differential fluid, with the latter offering better performance. The frequency of changing differential fluid depends on the manufacturer's recommendations, typically every 30,000 to 50,000 miles.
What gear oil does a Ram 3500 take?
75W140 or 75W85 GL5 gear oil meets 68218657AB, 4874469, 68218657AA, 68218657CA, 68218658CA rear differential limited slip fluid specs for select 2019 - 2022 and onward Ram 3500 models.
What is the difference between 75W90 and 75W140 oil?
The big difference between the oils is the kinematic viscosity. While 75W90 has a kinematic viscosity of 13.5 - 18.4 mm²/s, 75W140 has a kinematic viscosity of 24.0 - 32.4 mm²/s. Thus 75W140 has a better viscosity-temperature behaviour. The transmission oil can withstand higher loads.

What is the best diff fluid for a Ram 3500?
Differential gear oil and transfer case fluid specification capacity notes: The 2019-2022 Ram 3500 recommends the use of SAE 75W85 API GL-5 gear oil in the front differential and SAE 75W140 GL-5 with limited slip in dual rear wheel differentials (aka dually).
What kind of oil does a 2017 Ram 3500 6.7 Cummins take?
Model years 2007.5 to 2018: Choose a synthetic 15W-40 oil for temperatures above zero degrees Fahrenheit. For driving in all temperatures, including those below zero, choose a synthetic 5W-40 oil. Model years after 2019: Choose a synthetic 10W-30 oil for driving in temperatures above zero degrees Fahrenheit.
