I have a 6.1 as well. Normally cruise at 70mph and can achieve nearly 40mpg so if you are bimbling around at 60mph your 48.7mpg sounds feasible. Have you taken the kitchen out though to reduce the weight?Resurrecting thread to ask a question.
Life is a journey in our Ocean so we drive everywhere at 60mph, pretty bohemian. This 6.1 was showing 48.7mpg on a 150 mile th motorway trip but when the fuel gauge got to its first red light the range showed as 95 miles. I topped up after 20 miles when the range displayed 85.
Have I got an ultra efficient Ocean or do I need to get it checked out?
