Well, Its time to do the COMPLETE fluids change on the 04 XJR.
And with the accolades of modern technology, I'm left wondering what fluids to use.
Thanks to 'Victor' I have learned of the Shell naming behind the ZF transmission fluid.
But what about:

Manufactures, specifications, known accolades, pricing.
Simply put I am going for maximum performance and maximum life... Yes, I want it all ;-)
Brake Fluid: Should I consider DOT 5?
Engine coolant: So many choices! What do you think?
Engine Oil: Motul is probably overkill. I'm using Castrol Edge full synthetic, currently.
Power steering fluid: No idea here. And I am leery of the claims by the manufactures alone.
Spark Plugs: Again, so many choices.
Tires: I have been very happy with Michelin PS2. But this year I thought I'd try the Continental Extreme Contact.

Looking forward to everyones thoughts.
Guy.
