    Default Erratic fuel economy MPS3 - any tips?

    Hi,

    I've only driven my 2006 MPS3 < 1200km, but am noticing fuel economy has been inconsistent so far. Perhaps I am expecting the impossible and it's early days with the car, but I drive like granny 90% of the time. Been fuelling with BP Ultimate so far.

    Tank 1: 400km/50L, city driving
    Tank 2: 380km/50L, city driving - bought fuel at different BP and found performance of car not as good
    Tank 3: 350km/25L (!), freeway driving

    Any tips/checks - should I clean the MAF sensor?

    Thanks

    JB

    looks ok to me....
    12.5L/100km around town, 7L/100km on hwy...
    these cars are horrible in stop-start traffic around town... boost comes on easily, and fuel goes out the exhaust pipe

    Sounds about right to me.
    Nothing to worry about

    Fair enough - can understand. Brilliant on freeway though! I'm probably getting better economy than my last car though - a very worn 1989 Honda Civic, 1.5L, was getting ~ 12L/100 before it's demise

    I average 8.6L/100KM (only ~1,080KM old)

    Tank #1 : ~470KM
    Tank #2 : ~500KM
    Tank #3 : 110KM (so far)

    I don't really do much stop-start driving though. My trip to work is only ~10KM (each way) and is mostly back roads.

    On the way to and from Kwinana Motorplex (Woop-Ass Wednesday Drag Meets) my fuel economy isn't at its best

    A 20km difference from two full tanks is not erratic, it is normal. Two different batches of fuel, two different results.

    If it were two tanks of city driving with a 200km difference that would be cause for concern

    I find the more fun your car is the less fuel you have when your finished having fun

    I've also found bp ultimate to not last as long as caltex vortex 98, I regularly get 550 per tank

    I have put 55-56 litres in to mine once. Was shitting it that I would run out of fuel.
    This was coming back from down South earlier this year.

    I have used bp always but been meaning to jump to caltex or united as I just don't get consistent mileage anymore and that's from the same servo, I just don't trust the 100ron as I here it's just dosed to the s$&amp;@hause with ethanol
