    Default 2.2 Direct mpg normally this bad?

    I have a 04 registered 2.2 direct injection petrol Signum automatic. It has had fuel problems which have meant it has had a new high pressure fuel pump and sensor. However the fuel consumption I have always got out of it (before and after) is 19 mpg around and about and the best I have got is 29 mpg on a run. The car is not driven hard, and I live in what I would describe as normal town, so with reasonable traffic, and only a few hills and it's only done 34000 miles. (I also have and old 2.2 auto Merc but that does typically 26/36mpg on the same trips so I was expecting better with the lot newer car)

    I know that peoples experience with mpg varies a lot depending on there circumstances and driving styles but I would like to know if this typical real world mpg from a 2.2 auto Vauxhall and if anyone has suffered bad mpg on one of these and managed to get it fixed and if so what was the cause.

    I don’t think that the fuel pump and sensor being replaced has cured an underlying fault. They were replaced on separate occasions after the car cut out registering a fuel pressure fault and it has just cut out again today and doesn’t start till its been standing a while.



    Any comments from experience would be very helpful. Thanks.

    That seems high consumption to me mate, I have the less economical non-direct 2.2 and mine will get 38mpg on a motorway run, and around 25mpg round town!

    Something is definitely not right!

    does seem low, mines a 2.2 direct manual and i get about 31 mpg according to the trip computer which is a mix of short motorway and round town runs so would say something is not as it should be!

    our old 2.2 auto used to struggle to beat the 25MPG i was getting out of the 3.2... so if you're getting better than that, then i'd be impressed..
