What kind of rear differential fluid does a Ford F250 take?
The Ford F250 Super Duty truck typically takes a 75W-90 or 80W-90 gear oil for its rear differential. This is a common type of gear oil recommended by Ford for the rear axle of their heavy-duty pickup trucks.
Rear Differential Fluid for the Ford F250
The rear differential in a Ford F250 is responsible for transferring power from the transmission to the rear wheels and allowing them to rotate at different speeds when turning. To ensure proper lubrication and operation of the differential, it's important to use the correct type of gear oil.
According to the Ford F250 owner's manual and technical specifications, the recommended rear differential fluid is a 75W-90 or 80W-90 gear oil. These designations refer to the viscosity of the fluid, with 75W-90 being a slightly thinner oil compared to 80W-90.
The 75W-90 or 80W-90 gear oil provides the necessary lubrication and protection for the gears, bearings, and other components within the Ford F250's rear differential. Using the proper fluid helps to reduce wear, prevent leaks, and maintain the differential's performance over time.
Reasons for the Recommended Fluid
There are a few key reasons why Ford specifies a 75W-90 or 80W-90 gear oil for the F250's rear differential:
- Viscosity: The 75W-90 or 80W-90 viscosity is well-suited for the operating temperatures and loads experienced by the rear differential in a heavy-duty truck like the F250.
- Extreme Pressure Additives: These gear oils contain specialized additives that provide extra protection against wear and scoring of the gears under high loads and torque.
- Compatibility: Ford has engineered the rear differential components to work optimally with this type of gear oil, ensuring proper lubrication and long component life.
Using a gear oil that does not meet Ford's specifications could lead to increased wear, leaks, and potential damage to the rear differential over time.
Changing the Rear Differential Fluid
It's recommended to change the rear differential fluid in a Ford F250 every 30,000 to 60,000 miles, or as specified in the owner's manual. This helps to remove any contaminants that may have built up and ensures the fluid maintains its lubricating properties.
When changing the fluid, be sure to use a 75W-90 or 80W-90 gear oil that is approved for use in Ford rear differentials. Consult the owner's manual or speak with a Ford service technician to ensure you are using the correct fluid for your F250.
What kind of fluid goes in the rear end of a truck?
If you haven't guessed already, the differential relies on differential fluid (aka gear oil or differential oil) to stay working in peak condition.
What oil should I use in my rear differential?
75W90 GL-5 Gear Oil
The go-to gear oil for most differentials.
How much fluid does a 2016 Ford f250 rear differential hold?
3.5-7 quarts
Rear differential: 3.5-7 quarts for the 2011-2016 models and 3.1-3.78 quarts for 2017-2020.
What kind of fluid does a f250 rear diff take?
75W-85
BLAU Ford F-250 Transfer Case Differential Fluid Change Kit includes the correct amount of synthetic Mercon LV transfer case fluid, 80W-90 front differential gear oil, and 75W-85 rear differential gear oil. Gear oil kit fits the 2017-2023 Ford F-250 with Sterling 10.5 rear differential.
What kind of gear oil does a 2015 f250 take?
Get the 75W-90, 80W-90, or 75W-140 gear lube you need for your Super Duty.
What is the difference between 75W90 and 75W140 gear oil?
Thus 75W140 has a better viscosity-temperature behaviour. The transmission oil can withstand higher loads. Just because 75W140 is at first sight the more powerful oil, you can't always prefer 75W90. Always refer to the OEM instructions for your vehicle to determine which oil can be used.
How often to change rear differential fluid in a Ford f250?
In our example above, Ford recommends changing differential fluid every 150,000 miles in normal service. But they drop the change interval significantly – to every 30,000 miles – when towing frequently at wide-open throttle and driving at temps above 70ºF.
How do I know if my F250 has a limited slip differential?
To determine the axle ratio of your vehicle, locate the two-digit axle code first, then use your vehicle's towing guide to find the axle ratio that corresponds to that code. If your vehicle has a limited-slip differential, it will be noted as Limited Slip.
What kind of fluid does a 2018 Ford f350 rear differential take?
SAE 75W-140
In our case, we're using an SAE 75W-140 viscosity, with a GL-5 Limited Slip specification. The correct fluid level is achieved when a stream of fluid begins overflowing from the differential fluid fill port. The fill capacity for the Ford F-350 Dana 80 rear differential is 4.0 liters or 4.25 quarts.
What kind of fluid does a Ford rear differential take?
Rear Axle Oil SAE 80W-90 C2.
