You are sort of correct.
Most of our fuel comes from Singapore and our prices are based on the TAPIS price in Singapore. Asia runs on diesel there is an issue with a steadily growing demand for diesel and a tightening supply so the price is high. Simple supply and demand economics.
I suspect another underlying reason in Australia is that the majority of diesel is purchased by business and business is not as price concious as retail consumers so there is no huge reason for the oil companies to kill themselves with competition.

But the other thing that needs to be taken into account to split the difference between petrol & diesel even more is that loading up a petrol wagon with people and luggage or even putting a trailer behind it, the diesel will leave the petrol both in economy and at the lights. The diesel has 350nm of torque where as the Petrol only has 280nm. That torque split makes a big difference to loaded up acceleration and cruising, and that's where the diesel will win out even more.
So Tunes, dont go dragging you old man away from the lights or up hills if your loaded up with mates in your petrol RS, otherwise you might be a little embarrassed.

Too true. Also, if you are heavy footed in a diesel, it doesnt have as a big impact on your fuel economy. To acheive 8.8, I am almost short shifting and being very conservative around town. As soon as I get the right foot urge, it all goes out the window......

I know I've cheated but my petrol engine has up near 350Nm of torque now.

BUT.... there is a definate fuel economy hit when the kids are in the back (and they only weigh 70kg combined).

When I bought mine (mid-200

, diesel was significantly dearer than PULP. Daily running costs based on the factory fuel figures were near equal <$1 difference.

I also looked at using public transport - abot $1 a day more expensive to take the train & 2 hours more travel time.

Trip to Canberra with 2 mtbs on roof racks, 2 adults, luggage and biking bear for the 2 adults, averaged about 8.9 l/100km for the highway segments - closer to 10 for the weekend overall - given the heat over the WE airconditioner was earning its keep - car had 1540 km on the clock when i got home so i can now start exploring the cars potential

To stay sort of on topic. I downloaded an iPhobe App called Accufuel (cost all of $1.20 or so) which seems to have a nice interface for keeping fuel consumption records and it even shows L/100 Km if you want.

well... i have diesel... hpw about getting around 2 litres per 100km

i have proofs

Fair enough. Obviously not around Coogee unless they have stolen all the hills and there's been a nuclear explosion to get rid of the perpetual traffic jams.

So, to get your 2l/100km how frustrated are the vehicles & drivers around you? Daryl Eastlake & I managed (IIRC) <4L/100km over 200km in an automatic Golf5 1.6 a few years back but the traffic around us was spewing.

I was bored at the traffic lights so I tried a little experiment. I turned the AC off and watched the l/hr change. After trying it a couple of times I now know that it costs 40 cents/hour to run the AC (based on $1.20/lite for diesel).
At 20,000km per year with an average speed of 60km/hr and having the AC on for 50% of the time it will cost you $66.00 or somewhere around 50 litres of fuel per year.

That's today's fuel/cost saving tip.
