Re: Which lubricant should I use for my bike chain?Which lube that is the best is almost a religious question for some riders, so you can expect a lot of different suggestions. IME frequency of care is more important than what products you use, as long as you stay away from some obviously poor choices.
WD-40 isn't good(although better than nothing)
3-in-one isn't good(although better than WD-40)
Motorcycle chainlube is excessively sticky for bicycle use.
I tried medical grade white oil for a season. A dream to handle, but it seems like I got chain elongation worse than ever before.
Used a regular engine oil(same as in my vintage car) for several years, seemed to work just fine.
Am now running a boutique oil(Chain-L) which, judging by the smell is based on a hypoid(gear) oil. Very nice dribble characteristics during application. Kills a squeak just as well as anything else and otherwise seems OK.
Experiences with "dry" lubes vary between riders. Some swear by them, some swear at them.
One fault many people do is that they don't wipe their chains down well enough after oiling. Basically anything left that's more than a sheen on the surface is more than you need, it's inbetween the parts where the oil will do most good.
A chain that's too sticky on the outside will act as flypaper for grit and dust accellerating drive train wear.
