After selling my K&N panel filter and putting the stock air filter (albeit a clean one) back in I am now showing 38.0mpg. Had I had my K&N filter I reckon 40+ may have been achievable.
Had 1/4 tank Friday lunchtime so I put in £35 at 111.9p for a full tank (Shell 95) which then lasted getting home Friday after work, going into town this morning and then from Dunstable to Eastbourne via M1, M25, M23/A23, A27 and A22. Then back up the A22/M25 to Bagshot and then from Bagshot along the M4 to Tilehurst in Reading and then back home via M4, M25 and M1 and my orange 50 mile warning only came on when I was putting the car away in the garage.
What a brilliantly smooth V6 engine!!!!
What a car!!
why oh why oh why do you want to sell it lol
