I'm going to bring this old chesnut up again. Lately iv been filling up at morrisons to do my usual commute 84 miles daily. I was averaging 49mpg which I thought was a little shabby as iv achieved mid 50s previously. Anyhow I had this for a while then went past sainsburys one day on the way home as saw 127p a little so I filled her up first time ever at sainsburys. Since filling her up the trip computer has been reading consistently 4 plus extra mpg on all my journeys. Makes you wonder??? Also on the morrisons fuel I thought the car was sluggish pulling away on the motoway and overtaking etc. But lately is been better and seems more responsive. Does fuel actually make that big of a different???? Happy arguing
