Hello to all,

Just a quick question. After 8 years I've decided to replace the oil on
my Marzocchi MX Pro ETA 120mm fork... Great fork by the way.
Below is a photo of the oil that was in the chambers.

The left is from the left leg that has the ETA and the spring. The right
one is from the air chamber and is actually like new! The left oil has
become dirty and thinner. My question is if the dark color is from some
kind of oxidation from the spring (?). The seals work like new and there
is no oil or air leakage whatsoever.
