Hi Tomo!
Haha fuel consumption is the thorn in the side of what is otherwise an excellent vehicle. At worst im getting 22L/100km around town. At best is 10.5 on the freeway. Generally it sits between 17-20 around town, though a short stint on a highway will get that down to 15.
I think some of it is due to extra fuel required when the motor is cold. It doesn't take long to warm up, but i have noticed if it's just doing 5 minute trips the fuel consumption is higher than if it was doing similar driving for a longer period. But one of the reasons i bought a petrol is 5 minute trips are hell on a diesel.
I originally worked out fuel differences using a 20c/L (or maybe 10, i cant actually remember) difference in cost for premium vs diesel, and a 5L/100km consumption difference (10 vs 15), and calculated that it would take 200,000km to make back a $10k price excess on thw diesel. That doesnt include differing service costs.
Premium has been cheaper up until last week, and my consumptions been a little more, but even if you halve that estimate its still a lot of kays until you break even. But if you need the range the diesel is the way to go.
I do have an ongoing thread which shows some of what ive been up to here:
