Royal Purple will cause the MDS to shift a lot harder. There is a thread on this already. Never use anything outside of OEM when it comes to certain thing.

Royal Purple would be fine in my 3.7 with no MDS but would could cause a disaster for your engine.

Aye....I've only ever used mobile 1 in any of my engines. Nothing but good experiences.

I used mobile 1 75w140 in the rear diff today with about 4OZ of limited slip additive. Seems to be OK so far. I have the faintest amount of seepage from three of the bolts but everything else seems good. I used about a 1/8 beed of RTV. Think that was enough? It should cure by tomorrow and I'll wipe it clean and see if I get anymore leakage.

I bought 2 bottles of royal purple for the front but can't find a 14mm hex Allen wrench to get the fill plug out. Going to tackle that this week.

Nice. I went to advance, auto zone, sears and home depot. No luck.

I'll check ace tomorrow. Thanks.

I agree....but think it's a sham that Chrysler specifies mobile products only. Threes no way they engineer their own stuff, it's gotta be rebranded. Don't you think??
