WD40 alone should never be used as a lubricant. It dries and evaporates fairly rapidly, that it will not provide much lubrication after only a few hours. It is, however, GREAT for cleaning a chain, and removing gunked on grease.

I use WD40 for cleaning the chain off, getting any dried lube and gunk off, then apply DuPont multiuse Teflon lubricant (for bikes) on there. So far, so good: 23,000km and the chain is like new.
