Blood hell Stan! I know you have the 3.0 but you must have a much lighter touch with your right foot than I do  2017 4.4 SDV8 Autobiography

As long as your brakes aren't binding and your tyre pressures are right then your MPG wont be much different to anyone else doing the same trips in the same car.
I've never achieved any of the brilliant MPG figures that I've seen claimed for any car I've ever had. My experience is that the on board figure calculated by the car is very optomistic (blatant manufacturers lie!) and easily manipulated by selective resetting and carefull throttle use.
Over nearly 200K of miles in various L322s I've found that my 3.6s would show an average of about 24MPG (but I could easily exceed 30MPG by selective resetting) and brim to brim would show 20 to 22MPG. My 4.4 shows an average of 27ish MPG (over 35MPG with selective resetting) and brim to brim is 24 to 25MPG.
Personally I think these are amazing figures for a 2Tonne+ 4 wheel drive brick with a V8 engine in it. They're not what you'd spec on a car where fuel economy was a priority.

I used to use that road a lot and it's downhill....plus a 32mph average means you must have been tucked up behind an HGV!  MY23 Panamera E-Hybrid

mid 20's apparently.

Im more interested in what you get from your XJS. My old V12 used to delivery a steady 15mpg

Owned one of these for 13 years - averaged around 13-15mpg around town, could just break 20mpg on the motorway at a steady 70mph, towing a horse trailer, 10.9mpg.[/quote]
yes, getting 15mpg or a bit better RR 2005 4.4 petrol

i have same year 4.4TDV8 my long term according to the car is 26.8 this is running kids to school and shopping trips mainly rural and town roads, i generally get 450 from full to just under 1/4 tank which is usually my fill up point.
If i go on longer runs then that generally gets me to 30-32. 2012 Vogue 4.4 TDV8 - Current

Have just done a real time test. real Avge was 25.6 Mpg. Thats mainly town driving (lots of stop and start which is hard for this car) and some dual carriageway. I went to Cornwall last month (350 motorway miles) and got 30.6 on the computer. That was at 75 cruise. on fill up it showed 500 mile range for the first time ever! normally range shown is 475-490.

Overall mainly 23-26 real time MGP.

You can always get a lift to stretch the mpg further....
