Just for laughs - I'll post this. Had a customer come in with a KMC corrosion resistant chain the other day. This guy is totally OCD and completely cleans and lubes the chain AFTER EVERY RIDE! Thing is - with 4,000km on the chain - there was absolutely NO MEASURABLE WEAR.
The store manager was disgusted because normally that kinda milage usually means a new chain but I measured it and he conceeded defeat. The lube was oil based but the frequency and OCD cleaning probably counted for more.
