How often do you really need to change differential fluid?

every 30,000 to 50,000 miles
In most cases, you will need to change differential fluid every 30,000 to 50,000 miles. It’s important to stay on top of changing differential fluid because metal-on-metal contact creates heat from friction. It also weakens gears and wears down surfaces. That can lead to differential failure, which is a costly problem.

What happens if you don’t change the differential oil?

If you never change your differential fluid, you will start to notice strange sounds and bad smells from your car, before your diff will inevitably fail. This is not only costly to fix, and highly preventable, but can also be dangerous as you won’t be as in control of turning your vehicle, especially at high speeds.

How do I know if my rear differential fluid needs replacing?

Weird Noises

Do Subarus need differential fluid change?

Just like the oil inside your engine requires replacement to maintain maximum protection, so does the oil in your differential. Anytime there are moving metal-on-metal parts, lubrication is important and the oil will break down over time. Give our Service Department a call to learn more.

What happens if I never change my 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.

At what mileage should rear differential fluid be changed?

every 30k to 60k miles
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.
