Going from a 1.9 gttdi 110 asv lump, I used to get about 55 driving a round town, that was with a come air filter and a egr delete. The v6 gets about 40 and just 50 on a run. Is this the norm? All it has is the cone filter. And no idea of last service but can't afford to do one just now as money is tight with baby and getting married. As soon as I have it I will do because I'm a firm believer in if you look after your car, it will look after you. Thanks all
