Fox 36 Grip X : Oil quantity ?

I rode 60 hours on MY rise LT and I find that the fork's performance has already decreased. I'm going to do a basic maintenance by replacing the oils.
what type of oil and how much should I put on the left and right?
I don't understand the fox website and I'm very afraid of making a mistake.
but I also want to learn how to do it myself.

thanks for your help!

I circled the two types of oil and the three locations than you need to apply it.

You can also download the service manual, which will show you the step-by-step instructions.

Thank you !

If I understood correctly:
Air-Side bath is the part located on the left side at the bottom of the fork (when I am on the mountain bike) which corresponds to the air part. 10cc
Air Chamber is the upper part of this same side, i.e. under the air pressure valve. 3cc
For me the 2 parts are separated by a piston so oil is needed on each side.
Damper-Side Bath is the right side of the fork so the damping side. 20cc

You got it, brother!
It's not all that difficult, as long as you pay close attention to what you're doing. Keep everything clean, some of the fasteners are small and delicate, and there are tiny balls in your adjusters that are easy to lose.

thanks!

Does the "Air chamber" part also need to be drained?

In the tutorials available on you tube, only the lower parts seem to be drained.

Technically no.
You can do a lower leg service without touching the top end as the bottom sliding parts are not pressurised and come off as a separate unit.
But if you want to put some oil in the positive air chamber to lube the air piston, then release the air first or it will end up being stuck in your forehead

I feel like that's what's going to happen in any case!

I'll stick to draining the lower part. And in that case, no need to drain the air from the fork?

Well it's part of the service to add a little bit of oil in there!
Easy enough to do but ideally you need a flat faced socket for the top cap.
You can also remove any spacers and see if the forks really need them fitted.
