Well today i filled my Xtype indianapolis up with unleaded from tesco as it was 1.11 a litre 3p a litre less than the local bp.....i will be sticking to premium fuel, as noticed today my fuel consumption has dropped, only been tatting round town and already the gauge has come off the full, When i used bp fuel it took around 3 days to move the needle..so for the sake of 3p a litre i will be sticking with premium fuel....anybody else noticed the difference between fuel at a garage and fuel at a supermarket
