These 3.5 FWD auto sedans are damn good. Did a country trip 800 odd km from Sydney to Dubbo, to Mudgee and back to Sydney with some driving in each city and Trip computer showed 8.9l/100km while my calcs showed 8.8. Around town I am getting 10.1. Taller gearing would improve the country consumption. I noticed the final ratio on TL and TW is different form the other third gens. BTW my car is series MY02, with 4 speed auto.

Sounds about right for the consumption, i used to get below 8/100 when the car was empty and with the cruise on, but with the blower now its a tad higher now :badgrin:

yeah there pretty good
on a trip from newcastle to queensland
was getting 7.5 then with the a/c on went up to 7.9
that was with 2 adults and 2 kids and the boot chockers

better put in around town i get 11.0
thats with a few exited starts ;)

I'm currently getting 14.6/100 but my oxygen sensor is stuffed. Currently have it off ready to be replaced actually (thread is ****ed, getting that fixed tomorrow hopefully) and just driving around without one while i needed to today I've actually lowered the consumption ><.

Hopefully I should be able to get it to the low 11s when its all fixed up.

Yeh if you have a dodgy o2 sensor you can get better fuel economy without it, because the ECU just uses the default settings, instead of the wrong ones.

Fuel economy for the OP sounds about right. My car averages about 10.3 consistently (about 75% town, 25% highway). Been up around 12 lately, but we wont go in to why :badgrin: .

Fixed up the fittings today and reset the trip computer. Just coming home from the mechanic it seems to be staying between high 10s and low 11s which should save me heaps in fuel.

How much would a new o2 sensor cost?

Hey just a question about the fuel readings. On instand fuel read out, is it normal for it to show big numbers like 60.0ltr - 70.0ltr when accelerating from stop?

Mate told me to ignore the instant fuel read out unless I was doing constant speeds like on a freeway.

Your mate is right. It is perfectly normal. Instant fuel read out shows you how much fuel is currently being used, if you were to keep that load on the engine. So obviously if you could keep the engine running at 5000 rpm under load, fuel would be around 60L/100kms.

Only time i use instant fuel is on the freeway, and that's just to see how my foot compares to cruise control for fuel consumption, and for how much fuel i'm currently using.

I concur, because for me it is a battle and a half getting my car to anything within 12-13L/100km

I'm not sure that's *quite* right, since when you see those figures you are typically accelerating. If you hold it there it would be lower than 60L/100km surely.

Sorry i should have put more emphasis on the *could* part. Obviously you cant keep accelerating forever, which is why i said if you could keep the engine at that rpm under load (ie. accelerating) you would get 60L/100kms.
