Hello !

had the car about 18 months, have been getting consistently 530 + miles to a tank and high 40's MPG, (motorway driving) over the last few weeks I am noticing that I am struggling to get anything over 42 on a long run, any ideas? seems to be running ok ?

any suggestions would be greatly appreciated !
