If you use a can of lube per year....it's like pouring that stuff straight into the ground.
What? No.
The vast majority of lubes consists of two parts, a liquid thinner that evaporates relatively quickly, and a thicker grease/lube that is designed to stick inside the chain. The thinner evaporates and thicker parts remain on the chain until you wipe them off.
All that black crud that the chain picks up is lube mixed with dirt, there's very little that drips off (other than initially).
