  1. OnBoard MPG not matching actual useage

    Astra J/GTC
    I have an Astra 1.7 CDti estate. I reset the readings on the on board computer. After driving on and off for the full tank, I get a reading of 56.9mpg and then 504 miles covered. However, when I fill it up again it takes 47.61 litres to fill it up. So if you put those figures in 47.61 litres to...

    Ok so in February this year I serviced my car (1.9 cdti 150) and ran through a tin of BG244 as part of the process. Over the course of the tank the engine did seem smoother and I had an a small MPG increase of 2 (37-39) I then did some research on cleaners to run through with every tank in...
  3. Astra Mk4 G Convertible - 1.6 1V or 1.8?

    Astra G
    Hi All, I'm new, this is my first post! I have recently been looking around at Astra Mk4 convertibles with a view of getting one for the summer. My dilemma is MPG.

  7. Poor MPG?

    Astra H
    Firstly I apologise for my first post being about MPG! Last month I got myself a 2009 1.6 Astra Active+ 5dr. Very happy with it overall but a little concerned with the MPG I'm getting. Around town / shortish journeys I'm getting 30mpg, on a pure motorway drive I get 38mpg, this just seems a...
