I've just gave my 6 a service and changed the plugs just wanted to know what sort of colour the plugs should be after about 20k? Looking online this may indicate it's running a little lean or is this to be expected?

they look fine.

most of the guides for plugs are for carb cars usin leaded fuel.
Ah okay thank you!
oh, a 6 isnt a TU engine either BTW.
