Diff fluid hasn't been changed for 18 years.
I recently got a 2003 Honda Pilot with 300k+ miles from a family member and it's been wonderfully maintained except for the differential. As far as the previous owner is concerned, they haven't changed the fluid since they first bought it, and now I'm a bit concerned if I should keep it or not. The previous owner used the SUV daily, and knowing their driving style they really pushed the engine to it's limits. The car is now a bit sluggish, but still works wonderfully. Should I just change the fluid and call it a day or get rid of it?
Thanks, James
Should I just change the fluid
Of course. Cars need to be maintained.
but still works wonderfully. Should I ... get rid of it?
Does not compute.
Change the diff fluid.

This contradiction in the same sentence....hmmm 😞
It’s not like a transmission where you can get slippage after changing the fluid. Changing the fluid won’t hurt anything (if you do it correctly).
The question is how many more miles are you expecting? Most likely, if you are up to DIY, and you think the old thing still has some life left in ‘er, then yeah, change it. But I wouldn’t pay much to have someone else do it on a vehicle that may be near end of life.
