I'm not one to comment on these chain lube threads, but I ran out of chain-L a few months ago and decided to try something different, just to see if there was anything I was missing out on. One of the lubes I tried was Boeshield and it is not even close to chain-L. If you have not tried chain-L, you really should. It last 3-4 times longer than Boeshield. I cannot recommend chain-L enough, I just reordered and received my new bottle yesterday.
