Do NOT use lithium grease! That stuff will harden up and be IMPOSSIBLE to remove...it causes problems in the long run... ask me, with my 201K how I know this? :(
I would follow Charlee's advice. If one grease works for everything why would there be so many different kinds of grease. I'm sure any grease would work for a while but not all of them would be good for your machine in the long run. Companies spend thousands on research for what works best for their products so I would rather take advantage of their research and get what will be best for my machine in the long run rather than something that works now but might cause problems in the future.
