HP LJ4000N, jams in fuser.

I've always thought white lithium high temperature grease works best. But I have no idea where to get it right now. I tried using regular white lithium, and I was back in two months with the same problem. At this moment, I'm using regular old fuser oil--the kind we use to use on fuser units that got poured into those little pans and a wick roller would dip into it and carry it to the heat roller. I still have like ten bottles of that stuff.

Not all types of grease work. HP high temp grease is better. I do not recommend lithium grease.

So no silicone oil?

I think fuser oil is silicone. I'm pretty sure HP's fuser grease is silicone.
