Re: chain maintenance
I've been using motor oil from a squirt bottle for the past 30 years. I would never remove a chain just to clean it but will dunk one in a bucket of 50:1 if it's already off. I'm the only one in my small circle of friends that has not had a chain break or wear out yet. My theory is the layer of crud protects from grit and loss of lubricant.
Recently been experimenting with Green Grease. Not looking too good as it leaves a HUGE mess and the chain looks kinda dry after a while.
