On my road bike, I have a Campa 9spd chain that just refuses to die. Only the second chain this bike ever had... and it's on since july 2001.
Must have close to 10.000km now. (Wasnt riding much for over 15 years due to reasons such as being in the army and often being transferred between garrisions which made bringing a bike difficult, and later being a long-distance weekend commuter, so no time etc. Only really started riding again in 2020 when I got a job close to home).
Last half of these kms with drip-on wax (squirt lube).
My rigide mountain bike turned commuter / utility bike eats through chains like there's no tomorrow, though. Doesn't matter if original 8spd Shimano or cheap clone, doesn't matter if wet or dry lube, after 3000km they get noisy, and after ~4500km they're overdone.
Have to admit that the commuter doesn't get even half the love and care that the road bike does, even though it's much more useful. Kind of unfair, but such is life...
