Oil & Fluid change,,,,, How Often??

[VXR_DAZ]

I guess the answer is really how long is a piece of string, but how often should we be changing fluids other than engine oil? Should it be based on elapsed time (like 12 months or something) or based on how the oil/fluid looks?

I am thinking of:

Gearbox Oil
Diff Oil
Brake Fluid
Clutch Fluid
Power Steering Fluid

I feel a bit of a numpty asking but I can handle it

Brake, clutch, PAS fluid should be every two years. Coolant 5 years.

I believe once you have changed to the proper diff and gearbox oil you don't have to change again. (other than top up the diff with friction modifier when it starts to clonk).

Thanks, just found that in the Service Book, fancy that!!

I might get the gearbox and diff oil changed too, I'll consult the mighty fish

I have done all the above with the Royal Purple stuff, but what about the power steering fluid? my car was built in 04 so the steering fluid will be original I believe. How long will it last?
