Now, if you're not keeping the car, it doesn't matter. Sell it at 100K and it'll be running fine with the minimum care. But if your planning to keep it for a long time, spend a few dollars and change the drivetrain fluids.

And it's not just the metal parts. Oil degrades over time, going through all those heat cycles.
