hi i just got a TE 3.0L and my god is it bad on fuel i have cleaned the K&N and re oiled , new fuel filter and new platnium plugs in rear bank and normal plugs in frount bank no difference my next step is to get a new o2 sensor or are magnas just bad on fuel its also auto , thanks

cant really speak for the autos but my Manual 3L TE was excellent on fuel, how bad are we talking here?

How many K's per tank you getting? I get around 500+ out of a tank if I drive chill. 400ish if I take off hard at lights etc.

What kind of consumption figures are we talking here? In comparison to other large family cars (ie. Commodore/Falcon) the Magna is actually quite good on fuel. I have a 3lt TH auto with almost 290,000km and my figures are:

Highway - 7.1-8.1L/100km
Hwy/City Combined - 9.0L/100km
City - 9.7-10.4L/100km
"Spirited" driving - 11.5L/100km

This is on 95ron fuel as I was getting poor results (+1.5-2L/100km) on 91ron/E10 fuel.

If the consumption rate is any higher then about 14L/100km I would suggest having it checked out, it could be a burnt out o2 sensor or various other causes can cause bad consumption.

yeah, OP needs to define "bad on fuel"


14L/100KM?
18L/100KM?

well a 3/4 full tank i got 198ks on p/ul driving like grandmar

i have a 3lt manual TE and i usually get about 500km.. I drive through the city every day and often am tempted to zoom through traffic..

Ouch! Thats over 20L/100km from 95ron!

Edit - See Mal's post below :)

THis can be a hard one to lock down but check the following

Vac leaks
MAF sensor
o2 sensor
Exhaust Leaks
Dist, cap and rotor
Leads
Crank Case Ventilation

This is where you start, also how many k's on the car, how is your trans in so far as slippage and flaring etc

On a last note, you may want to actually measure litres per fill as you may be filling a tank that has a lot more fued in it than you realise if your sender is playing up
