WK diff lube

[nostaw]

So the WK is due for an engine oil + diff oil change. The engine is pretty easy -- I've got that before so I'll get the same stuff again.

Looks like the QDII requires 75W-140 gear oil + friction modifier for the ELSD. The Mopar oil is synthetic and is supposed to be changed every 12.5k mi (every 2 service intervals).

For my XJ I just use fairly standard stuff (e.g. non-synthetic) since it usually gets changed relatively frequently.

The WK is a DD and sees occasional towing use (I tow my XJ a few times a year, tow a boat or other small trailer a few times).

What do you guys recommend?

Go with what the owner's manual says for viscosity and blend types.

Synthetics tend to work better for heat and loads.

Well, I'm going to go w/ a synthetic 75W-140, but I was curious if anyone recommends a specific brand... Lots of stuff online, but...
