Retired but working with benefits.
Some limited slip fluid smells burnt when new and is dark color, but not black. Maybe someone can chime in and post a pic of new Mopar LSD fluid.

@Fitzz47 and @Maverick909:

out of curiosity, what fluid did you use to replace the original? I have been planning on doing this job and was leaning towards Royal Purple. Thanks!

I am at 17k. Was going to do it at 20k. Maybe I need to go ahead and change it.

Even on jeeps that have 1-2000 miles the fluid comes out pretty dark and stinky. Front always looks great but that’s more a function of the fad and folks generally not using 4wd a ton.

I've got 38K on mine and have changed the fluid 4 times. That's excessive but with lots of mud and water and the regearing it adds up. I use whatever fluid is on sale since it doesn't stay long.

It was easy to do and the oil was jet black.
There is a thread about rear diff failures in this forum (LSD Dana). In that thread some owners were recommending a fluid change at 4K-5K miles to help avoid the failures others were seeing.
