As I reported in February:
Presently, having bought a wholesale lot of X8s, I'm running an experiment to see how far the factory lube on a chain, highly spoken of by Sheldon Brown, will carry me without any lube being added. Currently at 600km without any visible ill effects. (When this experiment runs out, I'll fit my new crankset and stainless chain ring.)

The weather and a turn in hospital delayed further riding and also photography but I've now managed to take some photographs which tell the story.
This KMC X8 chain has been operated for 700km with only the lube with which it came from the factory. Sheldon Brown claimed that the factory lube would be good for 700 miles, so this chain has done about 5/8 that distance, and of course inside an enclosing chain case, rather than exposed to the elements and to dust in the air as is more normal on a touring bike.
However, I would say subjectively, that the Amar steel chain wheel, on which the paint was hardly scarred after 4600km when the old, regularly lubed, chain wore enough to replace, appears to be wearing faster under the chain with only the factory lube. The Amar was chosen to be a cheap temporary item which proved so attractive and effective and long-lasting, I kept it well beyond the original intention of swapping it out for something more prestigious in a hundred klicks or two. It is not surprising the top-notch KMC X8 chain preferred to wear the chain wheel rather than wear itself... (Not claiming that a subjective snapshot is conclusive, of course.)
The Hebie Chainglider is clean inside. Nothing has been flung off into it. The inside of the chain looks clean enough too. For purposes of comparison, I wore out the previous chain inside this Hebie Chainglider at 4605km, and that one was lubed from the beginning with Oil of Rohloff at intervals of 500km and then, when that proved superfluous, at intervals of 1000km whether it needed lubing or not; this figure (perhaps not impressive by comparison with some of the claims of ultra-distance chains on this board) is in itself twice as long as any other chain ever lasted on any bike with me.
Net result, after 700km, no visible or measurable wear on the chain, and evidence of wear on the chainring small enough to be qualified as "subjective". Not a conclusive test. Frankly, on the evidence plain to see in the photographs, I doubt that anything conclusive will be seen in under three or four times this distance, with only factory lube, say 2000 to 3000km. (We can conclude that Sheldon was right, that factory lube is "excellent" as he said, and that it will easily make 700m with no other lube added — but that's hardly a surprise: Sheldon wasn't often wrong!)
I've now replaced the Amar crankset with Stronglight Impact Double/Sugino Cospea cranks and a Surly stainless steel chainring, while retaining the KMC X8 chain which has already travelled 700km without any additional lube. No new lube has been added, and the chain hasn't been cleaned. The Hebie Chainglider has also been retained; I have no appetite for speeding up wear artificially merely for an experiment, which would undoubtedly be the effect of removing the chain case. I'll run it like this for another few hundred klicks just to see if there is any wear, and whether it is preferential (I expect the stainless steel chainring to wear the steel chain rather than the other way round as with the Amar/KMC combination). Those Phlllips vintage block pedals are not for sale, sorry.
Even more speculatively, this test if carried forward, and specifically as I have carried it forward, with best quality chains and stainless chainrings, see above, and see also Martin F's post on 12 February, may well offer evidence in favour of the "don't ever lube, the factory lube is good for the life of the chain" school of thought, especially when the grinding bits are run inside a chain case. It certainly offers an encomium to the Hebie Chainglider, but then we already knew that it is the best of the chain cases available.
The Amar crankset has been honourably retired to live in the Stronglight box, together with the 131mm Kinex bottom bracket required to make a Rohloff chain line of 54mmm, the crank equivalent of moving into a MacMillions Mansion...
... and, having moved so far upmarket, the Amars are thinking of appearing on a Thorn.
I am Andre Jute and I approve of this message.
