This, except I averaged 31mpg on a run to London at between 65/70 mph....In the 8000 miles since I've had my XJ8 I'm averaging 21mpg and that's based on probably two thirds local and one third motorway. If it was all motorway I reckon I could get close to 25mpg if I cruised everywhere at 60mph.
My 4.o litre will return on average 10.8ltr/100klm which works out at 26mpg Imperialjust out of interest i wondered what MPG everyone gets
i have a
2002 xj8 3.2
if im tootling around west yorkshire i can get 17 mpg (but thats taking it easy) on the motor way i can get about 27 mpg @ 65mph goes down to 24/26 mpg at 70/75 mph
Wow, sounds like a good trip - how did the Jag behave? Very few of our cars over that way.XJ8 3.2, 1998 167000 total miles. The last 4430 miles average 23.6mpg driving around South Oxon & West London, includes a 2200 trip to Monaco over the Alps via Menaggio on Lake Como in late May.
