Filled a Muslanne up from running on fumes to the brim today. 89L of Sainsbury's finest coming to a grand total of £115.69 .
What I did find impressive was the trip computer claimed a range of 360 miles which works out at 18MPG. Not too bad for a 6.75L twin turbo pushrod V8 which I believe is used mostly for town driving .
I put 100 quid in mine today and it confessed to 11.3 .....result
They are great aint they them Mulsanne
