I’d suggest there’s reasons why chain lube manufacturers don’t make lube like the chain manufacturers, but there could well be vested interests on both sides relating to selling you more lube or more transmission parts.
It’s partly about application methods. Gleitmo is only available in industrial quantities, and has to be hot dipped to penetrate into the internals of the chain. SRAM do this in their factory, but there’s very few of us who would bother to do that at home, or can afford to throw away the remaining bucket full of very expensive chian lube after dipping our one chain. Much easier to give it a squirt from a little bottle while turning the cranks!
But I also agree with with your suggestion that after market chain lube is becoming a bit of a racket. Gone are the days when we carefully applied a single drop of the precious nectar to each chain link. With the new chain lubes we’re urged to to flush the dirt away with a stream of the stuff – at how much a bottle!?!
So, who’s peddling the marketing ‘hype’ here? The chain manufacturers who provide your chain ready lubed with a high quality and expensive industrial chain lubricant, and suggest that for long service life of their product you leave it on for as long as you can. Or the aftermarket chain lubes and the bike shops that sell them, who tell us its just a storage protectant, to wash it off as soon as possible, and flood the chain with their inferior lubricant at every opportunity possible?
