    Fuel Economy at Idle 2.7l TDV6

    A question about fuel economy, when the trip computer is set to average fuel economy, does your fuel economy go up when the car is at idle??

    2.7l owners only please.

    Baz.
    Cheers Baz.

    Hi Baz - the fuel economy will decrease (average will go up) for all cars at idle.

    The average consumption will increase faster if you have just reset the trip computer, like after filling up.

    I can feel a remap coming on.

    Cheers,
    Rob

    Ah, maybe its only the 3.0 that idles up-hill too. Some hills need low range though.

    Economy seems a bit high, comparing it to the old D2 it is very high, considering the D2 had 3" oversize tyres, chipped, and all the crap on it and in it, this D4 has standard size tyres and all the gear now but when we first got it we did a couple of tanks without all the gear with similar figures.

    This is going on litres used and Ks travelled, not from the trip computer.

    With the camper on, 14.9l/100k.

    Baz - I recently towed a 2 tonne boat from Winston Hills to Bangor and got about 14.2 l/100km (on the optomistic!) trip computer. On trips down to Kiama, I am lucky to get under 10 l/100km. These were both with road tyres on and not loaded up inside the D4.

    AT/MT tyres will add another 1-2 l/100km and if stuff is on the roof racks - another 1-2.

    I agree that the fuel economy of the D4 is not as good as the D3. I am thinking seriously about getting a remap kit - in the couple of months.
