Don’t oil your stantions, use silicon spray then cycle the forks a few times after you clean the bike.
Pretty much all the wear i see on Fox forks in the workshop is to the left leg (air spring) and to the front of the stantion where the upper bush wears a grove in the left hand fork stantion – this can be mitigated by placing more than the the recommended amount of oil in the air spring side – fox recommend 20ml but i generally put 25 to 30ml in and i recommend that folk leave their bike upside down for a few hours each week to soak the bush and foam seal.
I see fox forks every week in the workshop with some form of wear to the left stantion but despite me reminding folk to get them serviced regularly and to take care of them they still seem surprised when a 6 month old fork that hasn’t been serviced and ridden hard needs £350+ of new stantions and crown/bushes seals etc.
It is a design fault, they could solve it in one easy swoop by placing a small grease nipple on their fork legs and using a very low viscosity grease to lubricate the seal and bushing but i doubt Fox would ever consider this as it would be an admittance of poor design, despite this i still bought a set of 2013 140mm Kashima Talas but then again it’s no hassle for me to strip them down every few weeks to change oil/clean seals etc as it takes 20mins all in.
