Everything I have ever seen about wd40 says the opposite. In my naive days I used to use it on my bike chains for cleaning and I reckon despite looking sparkly clean,they never lasted long after. It seems it penetrates too well, getting into all the seals and internal surfaces of the chain as well as the bits the sprockets ride on. It therefore forces out the heavier factory grease, from the bits that dont actually need cleaning but do most of the work of the chain. This means they simply fail sooner.
