Such good advice to freshen the clutch fluid yearly.
I reviewed my service records and see that I have rebuilt the clutch master cylinder every 100.000 km.
In the first 62,000 miles, I changed the fluid every year (8-14 months), six times. Except for once that I let it go three years.
In the second interval (68,000 miles), the clutch fluid was changed eight times averaging every other year, twice going to the three year mark. Bad docc. Bad.
Just a reminder, though, that I row my gearbox and flash my clutch like a jackrabbit on hot lava . . .
YMMV!
