WD40 is best lube IMO. Have used it for over 7 years and my chains barely even stretch and I have a high hp/tq bike. On can and website it even says it's used for chain lube as well. I even use it in place of neosporin when I have a cut...ok, j/k on that one. My bike is always on rear stand every night, so the next time I ride I get a paper towel, fold it up, and saturate it with wd40 and then rub it all over the chain as I spin the wheel slowly with my right hand. DONE. Takes me about 1 minute. Never spray it on because it gets too saturated and flings off just like anything else will. Sometimes I will also put it on after a ride so it's ready for the next day. Etc...etc...etc...has done wonders for me and thousands of bike owners. Most people who knock it are ones who never even have tried it too, which really makes me laugh. How the hell you going to argue something you've never experienced yourself.
