Any grease...
The "looseness" of the spec from Van's indicates any grease will do. Wheel bearing grease from the aviation department at Wallymart is fine. I had a can of Moly disulfide, so I used that on my hinges. Just felt like it, really. I could have used a dab of wheel bearing grease that I had too. It is certainly not necessary to search for one particular grease over another. Of course, oil is no good since it will drool out and disappear.
