I'm still working on a can of "Next Dimension" brand chain lube that I bought at an auto parts store in Shelburne, VT. It contains Moly & P T F E, and it wouldn't surprise me if the base stock is waste oil or assorted co-mingle product mixed with waste oil.
I can't say for sure if this product bothers any seals or O rings that may (or may not?) be inside the chain, but I'm not too worried about it.
My Triumph owner's manual reccomends Mobil gear lube. Some report the Mobil to fling off fairly readily, but it isn't a big deal to wipe the oil off the rim. I would probably use straight silicone as a chain lube as it should minimize dirt attraction, but I'm afraid of what it might do to the O rings if the two materials are not compatible.
I usually do what others have suggested - clean the chain, and oil it when it's warm, then leave it overnight for the excess to fall off. I don't suppose it would hurt to blow off the excess oil with compressed air either to minimize fling.
Just my two cents - if we keep the chain wet and reasonably clean, the rest will take care of itself with regard to chain life. Riding & shifting technique must surely play a role in chain life as well.
