    Default C5 diesel fuel consumption comparison

    I have been tracking my fuel consumption via the acar android app for a few years now. These are real "fillup" statistics, not the inaccurate trip computer figures.

    I had a 2006 2.0 litre HDi C5 that averaged 6.63l/100km's over 72638 km's. It had travelled 167000km when I bought it.

    My current 2010 3.0 litre V6 HDi C5 has averaged 7.083l/100km's over 17299km's.

    The V6 only has 32000 km's, so it's probably still running in.

    Pretty impressive consumption considering the awesome torque of the V6.

    Hi. Impressive low fuel consumption stats for the 3Lt V6. May I ask what is the Typical or Average driving that the V6 is used for?

    My job sees me doing a lot of country driving, but there is quite a lot of city driving too. Not a lot of peak hour stop/start driving though.

    It's driven normally too. I don't go out of my way to keep the consumption low. The massive torque is such a delight to power up hills and overtake.

    Ahh - country driving, warm engine, transmission, little stop/start will explain your lower fuel consumption.

    Out of interest, how do your empirical records compare to your dash fuel consumption readings?

    Computer is approximately 0.5l/100km more optimistic.
    Personally, I reckon the bowser always short changes you.
    If you put 10 litres of fuel into a marked jerry can, it never reaches the 10l mark.

    Sounds about right, I've had to C5 wagons the 1st a 4 speed, the second a 6 speed that averaged 6.5 and 6.2 respectively over 180K each. City/Urban/Country use.

    Now on my 2nd Picasso, both averaging 5.9.

    Of interest I yearly do a 1500 klm trip from Sydney to central west Qld in the Picasso and sitting on 120+ fuel usage increases quite a bit !

    Dieselman:

    My 2002 C5 HDI (2 litres) has consistently delivered the following consumption:
    On the highway, 5.5 to 6.0 L/100 km., with cruise control set at 95 to 100 km./hr.
    In the suburbs (very short trips) 8.5 to 9.0 L/100 km.
    These are trip computer numbers and my refill experience has given me complete confidence in their accuracy.

    Coffs Harbour to Sydney, 5.3l/100km in the C5 3.0 litre V6. Average speed 100km/h.
    Very happy with that!

    Per the trip computer, our c5 3.0 HDI returns around 6l/100kms for country driving, around 8l/100kms for city driving and so about 7l/100kms on average.

    My family owned a servo (roadhouse) years ago and it was difficult to short change the customer without big risks. The bowsers were checked by the gov't authorities and sealed. I'd assume it's still done.

    There are rules and tests for bowsers - http://www.measurement.gov.au/Documents/PetrolPump.pdf
