As I am new to filling up the XJ and doing long distances in it…..I am due to bring the car back to the Isle of Man on a temporary re-assignment….What sort of fuel consumption should I get going up the motorways? Car 3.6 Auto.
Thanks

Hi Jon,
On a nice steady run, in my experience, you’d ikely get 25mpg (if it were a V12 5.3l then you’d be getting around 17mpg).
One thing to be cognisant of interpretation of reading the fuel gauge in your can and how much fuel is in the tank when it reads 1/4 full. Until you’re sure of what you see then don’t trust that 1/4 on the gauge is actually a 1/4 of the tank of fuel – fill up early and carry spare fuel (though you really don’t want to run out as it will suck up crud from the bottom of the tank that you really don’t want distributing throughout the fuel system).
Better safe than sorry on your long trip to Isle of Mann to fill up regularly and then when on home turf to let the fuel levels lower and estabilish for yourself when exactly on the gauge the light comes on and how much there is in the tank at that point).
Hope that helps – have a safe and uneventful, though enjoyable journey

Laurence,
Thanks for the information….I am hoping to be able to do it on one tank from down South and fill up before the boat……The Super Unleaded over here is 130 or more a litre…lol.

OK…..not as bad as I thought it was going to be. Left Bishop’s Stortford on a full tank and got to Lancaster, refilled and cruising at between 60 and 65 all the way achieved 31.2 mpg!!!!!

As a newby to Jaguar ownership 31mpg is sounding great for such luxury and style. Very pleased I chose the 3.6 over the V12
