My $0.02 into the multipage thread: I use SRAM and always remove the factory grease/protectant/stuff (call it what you want) and apply my favorite lube. To me, a wet chain is a dirt/gunk magnet. I ride off-road and prefer "dry" lubes.

(If you really want to see a long thread, mention the words "WD40" and "lubricant" in the title and sit back and watch the train wreck!)
