The Mobil 1 grease does not contain moly. I've been using the Vavoline synthetic EP grease with moly on everything on my Toyota with good luck. The only place around that seems to have it is Advance Auto.
Some of the Schaeffers guys need to pipe up on this. They have a number of products that would probably work well. I'll be looking at those once my Valvoline stash is used up.
