    astravan 1.7 dti fuel consumption

    hi guys, had a good look at the threads to see if anyone has posted about mpg, but nothing exactly matches. hope you can advise.

    i've had a 51 plate astravan 1.7dti for 2 weeks now, replaced my 206 gti. one of the reasons for the new vehicle, apart from being a drummer and drums don't fit very well in a 206 (!), is i was hoping to get better fuel economy. i am getting better mpg than my gti, but not what i'd hoped.

    upon reading an ad on ebay for the same van as mine the guy stated that he gets 500 + miles from a full tank. i'm lucky to get 300 from mine, i do town and motorway driving, but 90 percent of the week the van is totally empty. (i may have a slighlty heavy foot from owning a gti!)

    is 300 on a full tank about right and the guy on t'bay was a bit over zealous with his advert? or do i have a prob? cheers. matt

    i used have 1.7 dti hatchback and would get 580 to a tank on motorway runs,around town 480/500 to a tank.
    so 300 is very poor to be honest.
    give it a good service,oil,air,fuel filter,
    should make a diffrence to mpg.

    right it's booked in for a full service tom for all the filters. hope that helps a bit! i've heard the injectors may need a clean too, is that redex stuff you put in the fuel tank any good for that or just hocus pocus?

    Is it very knocky when started cold, and then get quieter when warm, or does it stay equally knocky all the time?

    gets quieter when warm. only slightly though. it is a louder than my mates estate version.

    having always had a petrol car, diesel obviously sounds quite loud, plus a van is hollow! so don't really know if it's overly 'knocky' or not. it's a steady sound to the engine when accelerator is pressed. ?!?!?!?!?!

    If it is knocky I'd try getting the engine temp sensor changed, as the van may be stuck in warmup cycle killing economy (like driving an old petrol car with the choke out all the time).
