Some good info an tips here. Will try to follow and see if it improves. I've always thought they make some of these systems more complicated than they need to be but understanding it better will help. 2009 Range Rover Vogue 3.6TDV8, Bournville, Parchment/Navy

Mine does about 400 miles on a tank, so it's not that bad....  Pete

Pete, sounds good, but if you're having to drive it is such a way as to achieve 400 miles per tank..........

Going completely off topic here, but has anyone noticed that with a full tank and tickling the throttle the range on the dash will never go beyond 621 miles?

Sam, I said "mine does", not "I do".....  Pete
