If I use slick honey in the seals of my fox 36 grip2, does it get splashed by the damper oil? I was wondering if it will thicken the damper oil.
Maybe the damper cartridge itself is sealed from the leg of the fork since it requires bleeding. If so, why do we need do much oil in the damper leg anyway?
Thanks!

30ml vs 10 ml is a good question. It's also apply to the fit4

My guess? The 30ml volume of oil is required for proper hydraulic damping. The 10ml is only there for lubrication and cooling.

On the grip2 it could make sense. But for the fit4 everything is seal.

I would say yes, it's an issue and a reson that no grease is used by fox. The oil mixes with the grease and as a result gets thicker and can clog damper ports. The grip2 is very similar to the old Marzocchi damer that was on the 380. Marzochi was very clear not to use regualr grease. They said you has to use a very specific seal grease. This was the one Marzocchi recommended.: https://www.amazon.com/d/Water-Coolers-Filters/Dow-Corning-Molykote-55-Grease/B00B2OHYMU. The damper is sealed from the bath but over time oil gets sucked past the seal and adds to the volume in the damper. Thats why grip 2 has the self bleeding function where when it gets too full it dumps oil back to the bath.

Damper is sealed and separate from the bath oil. Bath oil only mixes very very slowly with damper oil via getting past damper shaft seal. The bottom of the stanchion on the air spring side is closed so volume for air and bath oil below it is limited. The stanchion leg on the damper side is open so there's plenty of volume to allow using more bath oil.

The mixing of bath and damper oil is very slow. The effect of any small amount of grease first mixing with bath oil then mixing with damper oil will be infinitesimal.

Great answer, thanks!
