14MPG , not too bad... like they say cant moan abouty mpg with a R.R TBH what do you actually want from it... and what good is all that performance with a veh shaped like a brick weighing more that a truck ? RR are for comfort enjoy, if you want speed.. get a Scooby

There is plenty you can do to improve economy, I have put Magnecor blue plug leads on and use platinum plugs, K&N filter, Janspeed cat back stainless zorst, and a pair of Tornado chips. I average around 20 using high octane fuel on my 4.6 hse. Next job is ported and gas flowed heads, ported inlet manifold with bigger trumpets. The engine has done 150K and is sweet.

As I said I get average of 14 mpg and gas is only 58p a litre so no complaints and with the remapping to give more mid range grunt she drives well and fairly skips along

I drive a p38 4.0 ltr with LPG conversion, returning the equivilant of 27mpg. Got to say that without the LPG I would not be driving a RR at all. Coincidentally, I will be fitting a hydrogen generator in the very near future and hope to further improve the burn and reduce the petrol consumption some more.
