I drive a AU falcon (I6) and the L/100 on the highway is said to be around 6.8L/100Km. I know this is an average under ideal driving conditions (also a well maintained and tuned car etc.). Now my car has been maintained and looked after etc. Now I've calculated that the 550km round trip to Twizel and back should theoretically use 37.4L, give or take a couple of L but when I last drove to Twizel and back. The figures I got were more of that of the city driving average (11.5L/100Km), around 63L. Odd how much the difference was. Am I missing something here?

Just done a little research and one car review on the AU says it's 10.4L/100Km on the highway and 14L/100Km in the city, this seems more realistic to my calculations. Anyone differ on this?

strange, my car is cammed and tuned for power and i can still get 7ishL/100km depending on weather
is the 11.5L/100 your city driving figure or is that the quoted figure? what are you getting around town?

11.5 is quoted. I couldnt give you an accurate L/100km for around town at the moment.

Down in the South Island where I live we don't have such things as highways, the most we have is 2 lane roads with speed limits of 100km/h. No 4 lane roads etc. And most of our roads are hilly which chews through the fuel which will explain the increased fuel useage.

im getting about 250-300 around town and 700-800 on the highway
when you say well maintained i assume you mean servicing but have you replaced the o2 sensor at all? a diagnostic tool will be able to tell you if its stuffed also other things to consider are fuel line pressure, fuel filter, fuel injectors perhaps a dirty throttle body?

Yes i mean servicing, no i havn't replaced the O2 sensor. Do you have to go into ford for them to plug the car into their computers to find out if its stuffed?

A bit more or less depending on roads/speed but close enough. Oh, as for the 02 sensor, I replaced mine at around 120K and noticed the difference (at the time was $50 for a Bosch off ebay) |

alternatively you could take it out and have a look, im sure youll be able to find a comparison between a stuffed one and a good one on here, there was a walkthrough "how to: change your o2 sensor" in the au forum, not sure who wrote it but its there somewhere and it had pictures of both

I had an AU1 4.0 auto futura that i'd seen over 900km on the DTE - North Island roads(they are actually sealed up here) - joking I was born in the south. My current AU1 V8 Ghia (so heavier suspension+options & V8) can cruise open road and hit 8.8Lt/100km (loaded with wife, 2 kids & all the baggage the boot can carry. Your fuel economy is what I have had out of previously owned AU XR8's. Its either cars state of tune(including basics like tyre pressure!), driving style, or roads that you can't really cruise on(i.e. that hill climb out of Dunedin would use half a tank alone).

FWIW, I get around 500-550 'city' driving........highway it's close to 750-800kms.....drove up to NSW a couple of months ago for holiday......trip computer was prediciting tank would get me just over 900kms for most of the trip, until a couple of stops mid-trip reduced it to around the 800km mark. That holiday was before I got my new exhaust / headers / ballistic cat......would be interesting to see what difference it made to economy.....

around town i still average about 450 to 500kms
i travelled from jimboomba to glenn innes towing a trailer empty now i think its some where between 300 to 400 kms to there, take about 4 hours and i went through half a tank and a little bit more, trouble is going through cunninghams gap and on the way to warwick is a shocker, you got a big mountian climb then the speeds goes up and down
