The best 2010 Jeep Patriot rear differential fluid
The absolute best rear differential fluid for a 2010 Jeep Patriot is the OEM lubricant recommended by Jeep itself: MOPAR Gear & Axle Lubricant SAE 80W-90 API GL-5. You can
buy it online here
. But what if the OEM oil is out of stock—or if you want a cheaper version? Any non-synthetic gear lubricant that meets the same requirements will work. If it’s listed as “80W-90,” that means it’s got the right level of viscosity, while “GL-5” indicates the level of sulfur-based additives in the oil, which help the lubricant operate smoothly under pressure. Check out the following options:
What is rear differential fluid—and why does your Jeep need it?
So just what is rear differential fluid? What does it do for your Jeep, and
why do you need to replace it
? Rear differential fluid is a type of motor oil that lubricates your Patriot’s rear axle, helping the car run smoothly. But more importantly, it allows the rear wheels to spin at different speeds. That’s especially important for off-roading, as it delivers variable torque to the rear wheels and helps you navigate uneven terrain and slippery conditions with aplomb.
How often to change 2010 Jeep Patriot rear differential fluid
Because differential fluid doesn’t have to work as hard as the supercritical oil that lubricates your Patriot’s engine, it’s easy to overlook it. In fact, your owner’s manual may not even list a specific interval at which to change this fluid out. But certain telltale signs might indicate that it’s time for
differential fluid replacement
: - A burning smell from the rear gearbox
- Whirring, howling, or straining noises
- Any unusual vibrations
In addition to keeping your eyes and ears (and nose) out for these symptoms of low or contaminated differential fluid, you can make your life easy and your Jeep healthy by changing the fluid every 30,000 to 60,000 miles. For a 2010 Patriot, Jeep recommends changing the rear differential fluid closer to the 60,000-mile mark, but there are a couple of cases where you may want to do this service earlier:
- If you use your Jeep for a lot of off-roading, it’s better to change the differential fluid closer to 30,000 miles.
- If you notice any of the symptoms above before you hit the 60,000-mile mark, change the fluid sooner rather than later.

How to change your Jeep’s differential fluid
Start by consulting your owner’s manual (we’ve got
a handy PDF copy
here for your convenience) to confirm the exact specifications for your Jeep. Then assemble the following tools: Step 1: Jack up the car so that you can access the rear differential. If your Patriot sits high off the ground, you may be able to get away with skipping this step.
Step 2: Remove the fill plug first. Why? Sometimes it’s hard to open that plug, and it’s much, much better to find that out before you’ve drained your differential.
Step 3: Once the fill plug is open, remove the drain plug and let the old fluid drain away into your pan. You might notice a nasty odor, as if somebody just cracked open a bunch of rotten eggs—that’s those sulfur-based friction modifiers at work!
Step 4: Put the drain plug back and use your pump to fill up the differential. The fluid level should be between the bottom of the fill hole and 1/8 inch below the hole—but you’ll know you’ve overfilled if it starts flowing out.
Step 5: Replace the fill plug, and you’re done!
