I've tried several lubes over the years and always come back to Silkolene Pro Lube. It is by far the best I've used.
Fully synthetic racing chain lubricant that produces a clean film designed not to fling off when applied, even when used between races. It incorporates a micronized laminar solid lubricant which, combined with advanced synthetics, gives outstanding lubrication performance. It is intended for use in road racing and off-road competition, but is equally suitable for street bikes and O-ring chains. The lube quickly penetrates to the pins and bushes leaving a thin, yet highly effective lubricating film, and offers excellent corrosion protection and resists shock loads, high temperature conditions and the exceptional 'G' forces experienced in racing situations.
