    Default 1.9 cdti 150 + 30 of diesel

    = 148 miles.

    Surely these things do more than this, that was sensible driving of a mixture of town and motorway roads. I bought this car as it should be cheaper to run than my v6 astra, its turning out its costing me more to run.

    Does this sound right to you lot, its just passed MOT and the smoke test couldnt even get a reading due to a lack of smoke so i know its not over fuelling.

    Due for getting rid due to costs of running

    Assume 30 of diesel is 21 litres
    and
    21 litres is 4.5 gallons
    Round 148 miles to 150 miles
    That gives 33 MPG
    That is quite fair for a single mixed journey, starting from cold at this time of year

    33mpg actually sounds quite crap in all honesty, my astra v6 manages 32mpg driving normally, starting to regret buying the vectra, done all the research before i bought it and most people were saying they were getting 40+mpg

    It's not possible to work out the running costs from one fill up of diesel
    Although you filled up with 30 of diesel, the normal method is to work out the fill to fill consumption, over at least five complete tanks (for the Vectra C this would then be 300 litres)
    Remember, don't calculate from the value of the fuel, it's the volume
    If it helps, fill up in 7 litre units, it makes the mental arithmetic easier

    Sounds a bit low Rick, I find you do have to drive a bit more sensibly with an oil burner to get the better mpg, mines currently around 45mpg 'normal' driving. I did find it worse with lots of short trips when the engine didn't get up to temp.

    Drivers swapping from petrol to diesel usually report this when upsizing from a smaller car to a larger
    This is usually due to selecting a lower gear than what is actually required

    Whereas a petrol might run at 3000 to 4000rpm at a certain speed, the diesel needs to be much lower and typically half that
    As a guide, for 70mph you want to be driving at just above the idle speed

    Nope, it's bad to have an engine labouring (which is as good as having an engine run above idle in the higher gears let alone top). Labouring means the engine is not burning the fuel properly and hence wasting it.

    There is no other rule other than at 70mph be in top gear. Use the other gears for acceleration. If diesel teaches you one thing it teaches you never to skip gears.

    You've obviously not driven a 3.0 V6 CDTI then or some of the latest diesel engines
    These run at just above the idle speed
    Equally, my two previous diesels returned the best MPG using this same method
    I am surprised you've not seen the same with your 1.9 CDTI
