Hello Experts and Members,
I own a stock 2009 Wagon with the ZD30 engine. As I live up in the lovely NT where there is hardly any traffic I average about 11L/100KM on average with city/suburb running.
However whenever we go on a trip averaging around 120-130KMPH I end up with a horrible 18L/100KM.
I know this is probably because the diesel engine is revving at almost 3500RPM, but I was wondering if anyone knows at what speed the Inter-cooler Turbo Common Rail ZD30 engine is most efficient. I'm guessing somewhere between the 80-110KMPH zone.
Some insight in this regard would be greatly appreciated.
Have a great day!
