Randal,
Chain wear is normal, especially if you have ever over heated the chain. The number one cause of chain stretching is heat from lack of lubrication, and getting the chin bound up in a log. At this point I would recommend replacing the chain and make sure that you fill the oil tank every-time you fill the fuel tank. They should run out at about the same time.
I hope this helps answer your question.
