Yes it's seems normal. I do a lot of motorway driving, the computer says 41 ish to the gallon. My calculator says 40 mpg. It's very god for a car this size.Well impressed.
Hi just joined the forum having got my 2012 XF a few weeks ago. I must say I absolutely love the car. Its a XF 3.0l S portfolio. I have never driven a car so quiet and smooth, the gearbox is seamless when changing. Looking forward to lots of effortless miles. Phil
