i would actually

help a fellow OCAU'er out (computer nerd, not car buff here!)

HLC - adaptive shift auto doesnt have power or economy mode i dont think...at least theres no button for it.

100% suburban driving, never go above 60, plenty of traffic lights. i do like to give it a bit of throttle coz i love the sound but it never really goes above 2500rpm (seems to pull along just fine with no need to get too excited!)

i really thought that 12-13l/100km would be a reasonable ask though with my type of driving, because i HAMMER TO HELL my dad's 3.0l boxer 6 cyl subaru outback in sport sharp mode and the trip computer never says im doing more than 13l/100km (i had it for the last two weeks to clear out all dad's sedate driving which would bring the average down ) - thats even when im regularly spooning it all the way up to 4500rpm in first and second around town. i obviously dont treat my own car the same...(dont worry, his is on a novated lease and is due for replacement in a few months)

I think I'll re[place my O2 sensor now because I'm going through fuel like you wouldn't believe and it pushing me to buy the new ranger which has 8.3L/100km. Last week I put injector cleaner in my car and took off the leads and plugs one by one and found that the number 1 lead the ring was split open so it probably wasn't firing too well. Fixed that up and already the economy has improved, but not good enough. Hope this helps anyone else.

Im average about 12l to the 100 from a S1 ute 5 speed non VCt for the daily to and from work trip in traffic in Sydney. The only mod on the ute is that it only has 1 muffler in the system otherwise bog stock.

I'm changing the Oxy sensor on Sunday, and will probably do plugs and air filter too (oil was done a few months back).

Fingers crossed we'll notice a difference !

Sorry Sanjay, my camera battery was flat (the mrs finished it off and didn't recharge it) so I havn't yet been able to take a pic. I'll have the mrs reveal the location of the charger in the morning so I can get the battery charged enough to get a few snaps.

Im getting 830km to 65 litres in a xr8 220kw manual on the highway, dont think i will be changing to the "MORE" ? economical 6 cylinder any time soon.

[HLC]

i think i set a new record for economy last tank...

18.5L/100km in my I6 LOL

and the oxy sensor is still good as the tank before that was around the 13L/100km mark, and im on track for another 13L/100km tank this time too LOL

After doing coil packs and leads my economy became much better, just gotta do O2 sensors.

My XR8 on average 18.6L/100km for the last 10,000km which works out to roughly $30 per 100km using Ultimate or V-power.

Missus BA XR6 13.3L/100km for the last 10,000km which works out to roughly $20 per 100km using normal unleaded.

I use 10,000km to get a decent average over time which seems to be more consistent for fuel averages, for my liking anyway.

It would seem to me from reading this thread that the thirsty V8 is a myth and it should really be the thirsty I6!

My fairmont in getting 11.6L/100km and I drive with power mode on, down the M4, King georges road and M5 tunnel everyday in the peak hour carpark in the morning and reasonably clear traffic in the evening. 75Km each way. 150Km a day. Go figure, My XR6 HP (manual) costs me as much to run as the Fairmont, and I run that on 91 and the mont on 98. I have tried babying the XR, short shifting, using 95, using 98, but I can't get the same economy as the V8!
Now with the flash tuner on the way, I'm hoping to get into the 10'sL/100Km based on the claim of 1-2 litre better fuel consumption. So no regrets when I get rid of the XR in a months time.

Meh ... I managed 24L/100km the other day ... mind you the loads I was carrying were pretty heavy all day ... and I had to do a freeway run carrying these







They were meant to be 120kg each ... they were more like 250kg each ... I really couldn't do more than 80km/h due to the buffetting ... was interesting when being passed by trucks.

I was stopped on the M7 just re-checking my load ... and took a few photos with my phone for evidence.

[poolkeeper]

I get anything from 9L to 11L per 100km's

I've been doing the same run each day/week for years; had a V8 NC Fairlane for 11 years and bought an AU2 in February this year. For the past 12 years I've always bought fuel (91 oct) from the same place (Liberty). The V8 used to average around 16L/100km, the AU2 has been doing around 12L/100km. And here's the odd thing. The service station I've been using changed hands last month and the new owners are ... so I've been filling up at the local Caltex with their 95 Premium. 3 tanks so far and the average has been around 15.8L/100km and the car feels rough and lumpy. I reset the ECU before this last tank but it has made no difference. I'll try another brand when this tank runs out in a couple of days, but the car is (otherwise) running fine, has just had it's 5000km oil and filter change, plugs, O2 sensor, coil packs etc are excellent and it's only done 80,000km anyway. Completely stock i6 Forte auto, by the way. Did a run from Adelaide to Newcastle and back a few weeks ago and averaged 8L/100km for the 3500km - but most of that is 110kmh on cruise control and on dead flat plains.
