I always used motor oil or WD_40 or whatever was handy when I was an ig'nint kid and cleaned my chain with a toothbrush and pipecleaners in a pie tin of gasoline in the middle of my dads garage floor. I also drank from the garden hose and never wore a seatbelt. How I ever survived to adulthood I'll never know. My, how bicycle drive train technology has come along. What I'd like to know is what is the stuff new chains come packed in. Some kind of grease I think, stiffer than oil. I've worked in a bike shop and I've installed hundreds of chains. The factory lube seems to be the ideal. Stays clean for quite some time.
