Depends. Can you post more info about your rig and how you use it. (manual or auto transmission, is it lifted, big tires, do you tow, where/how do you wheel, daily driver, etc.)

You may want to post in the stock (or modified) sections so more folks'll see it. Extreme is for major modifications, I just happened to catch your thread title.

Maybe an Admin will move it for you.

Moved to Stock and +1 on more info regarding your use of the JK.

I changed mine to synthetic at around 5K but that was due to mud slinging and submerging it now and then.

Change it every year at the very least especially if you off-road and enter deep water and mud.

Very simple preventitive maintenance job for anyone and much cheaper than taking into the Dealership. The JK has been my easiest vehicle for draining the diff's. appox. 15-20minutes each diff to drain and add new synthetic fluids. I have used 75W90 royal purple with no troubles.
