How often should I change my Subaru differential fluid?
The recommended frequency for changing the differential fluid in your Subaru can vary depending on your driving conditions and the specific model of your vehicle. However, as a general guideline, it's typically advised to change the differential fluid every 30,000 to 60,000 miles.
Understanding Differential Fluid Maintenance
The differential in your Subaru is responsible for transferring power from the transmission to the wheels, allowing them to rotate at different speeds when turning. The differential fluid lubricates and cools the gears, ensuring smooth and efficient operation. Over time, this fluid can break down, become contaminated, or lose its lubricating properties, which can lead to increased wear and tear on the differential components.
Factors Affecting Differential Fluid Change Interval
Several factors can influence the recommended differential fluid change interval for your Subaru:
- Driving Conditions: If you frequently tow heavy loads, drive in extreme temperatures, or engage in off-road activities, you may need to change the differential fluid more often than the standard recommendation.
- Vehicle Model: Different Subaru models may have varying differential fluid change intervals, so it's important to consult your owner's manual or speak with a Subaru dealer to determine the best schedule for your specific vehicle.
- Fluid Condition: Regularly inspecting the differential fluid can help you determine if it needs to be changed sooner than the recommended interval. If the fluid appears discolored, has a burnt smell, or contains metal shavings, it's a sign that it needs to be replaced.
By following the recommended differential fluid change interval for your Subaru, you can help ensure the longevity and proper functioning of your vehicle's differential, ultimately contributing to a smoother and more reliable driving experience.
What happens if you never change differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.

How often do you change differential fluid in AWD?
Differential Fluid usually lasts longer than most other fluids. The life of differential fluid is variable but a major difference between for example oil and differential fluid, is differential fluid usually is not filtered. Usually, differential fluid is changed after every 30k to 60k miles driven.
What is Subaru's recommended oil change interval?
The general rule for Subaru vehicles is to get an oil change every 6,000 miles and every six months, whichever comes first. With that said, don't go more than six months without getting an oil change, no matter how much or how little you drive.
When to change gear oil on a Subaru?
Subaru often suggests changing the transmission fluid at regular intervals, such as every 30,000 to 60,000 miles, depending on the model and transmission type.
What is the life expectancy of a rear differential?
To my knowledge, rear differentials under standard care/oil replacements should last the lifetime of a vehicle and this was further confirmed on a call with Subaru's Customer Service team where they confirmed up to "999,999 miles or lifetime of the vehicle".
How long does Subaru differential fluid last?
