That notion also falls flat on its face in my climate as does the notion that oring chains need very little lube. Folks tend to forget that there is no lube sealed inside the rollers of the chain. Sure the pins have lube sealed inside the sleeves in which they operate, but the rollers are totally reliant on external lubrication. Leave them unlubed and they wear prematurely, further causing friction especially as the chain rolls over the driving sprocket.
