..... LoobMan says they've put 100,000 miles on a chain with their system with NO significant sign of wear.....
That said... the DID X Ring chain found on the Speedmaster is top of the line stuff....
DID X ring technology
I've put 15,000 miles on mine with little or zero stretching apparent.... I've always use a block of parafin wax to clean my links and sprockets and then lubed with a product call "ChainWax" I think the approach fills the gaps in the links to where they are virtually sealed from exposure to grit that may migrate towards the seals.... The other obvious factor that demands attention is 'heat build-up' from lack of lubrication at metal to metal contact points like sprocket teeth and chain rollers...
Using wax IMO minimizes the loss of lubricant as it tends to flow when HOT and solidify when COOLED as it moves along the sprocket and chain contact surfaces building up in the areas where a more liquid material would be thrown of by centrifical force, thereby creating little barriers that prevent grit from entering into these exposed areas... Not completely but to a large extent. You need to start with a clean chain.
IF you can afford to buy a new chain after the warranty period is over and/or replace worn sprockets, then I don't see a need to ever lube unless a link or two have sticky plates.
