I have just bought a jag which has orange antifreeze that "must not be mixed with others" Looking at the Castrol website, it says "b. Cooling systems. Use Refer to main dealer at a concentration of 50% or one part Refer to main dealer with one part water. Models from 1999 (i.e VIN 042635 for XK8; 878389 for XJ8; S type all from first build and all subsequent models) use Refer to main dealer extended life coolant, coloured orange and MUST NOT BE MIXED with other coolants "
1) what's special about it?
2) must I buy it at the Jag dealer, or is the same spec available under a more common brand?
p.s.
I have heard (unconfirmed) that it is a Ford spec. Does that make sense?
