Normally, I would only spray it on my chain once in a year, and it would keep working all that year as long as I stayed out of rain. But this year, it only seems to work for a couple rides before having to re-apply again. If I don't, the chain starts making grinding noises when I pedal. I'm getting the impression that this stuff has gotten old, but I'm not sure how old it is now. Does lube actually expire??? I still have plenty left in the can. Here's a link to the exact product, although I didn't pay nearly as much as is being charged for it in the link. I think I paid less than $5.
