I've already ridden a new Campy 11 speed chain for several hundred miles using WD-40 as the only lube. So far, it's causing no problems at all. The chain stays just as clean as any other wet lube I've used. I'll post more when I have 1,000 miles on that chain and another that is being lubed with homebrew that has 80/90W synthetic gear lube in it. I'm betting there won't be much difference in the wear.
