Hey guys,

Have been averaging a high fuel usage of 18/20L per 100kms is this normal in an FG XR6T ute? Even when driving normal the best I can get it down to is around 16 litres. Also, the engine light came on today while the tank was nearing empty, and then the engine light went away when I filled her up..

I'm booked in tomorrow at the Ford dealer where the car was purchased for them to diagnose the problem..

Can anyone help me out here, what could the problem be and what are my chances of the Ford dealer finding it and fixing it?

Cheers

That is normal for me, as I do short trips as my work is only 10mins away in peak hour.

The economy all depends on how you drive it. Ford will plug their WDS into the ECU and if it says there is something wrong, then they should find it.

The problem will start if the WDS does not find anythign and they are then at a loss as diagnosis is not their strong point.

Thanks for that mate, do you think that there could be something wrong and that's why the fuel usage is so high? Is there any sort of problem where there is an engine light on and high fuel consumption readings?

Cheers

Just so you know ZAP has a GT-E so they are always gonna be more thirsty that an a turbo

Im averaging 10.4 in a semi rural area. Im thinking your consumption is a bit high

With the setup I run I'm still averaging 10/100 even when it was stock.

Once warm and say cruise set at 100k in 6th it should be around the 10.5 mark.

My expert diagnosis is you probably have a faulty oxygen sensor.

If so they should be able to pin-point it with relative ease at it would have logged fault codes.

I'm with tab... sounds like a sensor of some kind is way dodgy.

If I drive hard around town I never get over 14-15. I'm usually on 11.5 l/100. Mine a sedan, so I thought it would be worse round town.

fingers crossed the dealer find something.

Thanks guys!

Picked up the ute from Ford about an hour ago, got this.

ATTENDED TO ENGINE WARNING LIGHT COMING ON DASH

ATTEND TO ENGINE WARNING LIGHT COMING ON. SELF TESTED IDS TO FIND CODE FOR WASTEGATE FAILURE. CHECKED AND FOUND BLOW OFF VALVE MODIFIED AND REAR TYRES SCRUBBED. (LOL) CLEARED CODES AND RETESTED AND FOUND ALL OK AT TIME OF TEST. OWNER NOTIFIED US OF HIGH FUEL CONSUMPTION - HOW IS THE VEHICLE BEING DRIVEN? THIS WILL AFFECT FUEL CONSUMPTION (LOL AGAIN). NO FAULTS AT TIME OF TEST.

Are you serious? And you were legitimately concerned about your fuel consumption?

I got nothin'
