Big fuel consumption. Replacement of the sensor of oxygen?!!!!

[EDST777]

Hello. I own for EDGE 2008 3.5 Limited.My a consumption of gasoline around the city 19 liters / 100 kilometers (a city cycle). Outside the city on the route (autobahn) of 12,5 liters / 100 kilometers. I am disturbed by such big expense. My run of the car of 104 000 kilometers. I think to change all sensors of oxygen. Question to you, yours faithfully:
- what number of sensors of oxygen on this engine?
- there are people who already changed oxygen sensors?
I will be grateful for any information and comments. Thanks.

I currently have a 2011 Ltd but had a 2008 previous to that. I did get slightly better mileage with the 2011 compared to the 2008.

 

I remember getting around 13-14 L/100km city driving with the 2008. Although driving style influences mileage, your 19 L/100km seems excessive. Have you thought of having a technician look into it? Sensors might be the culprits, but could also be plug wires, bad programming of the transmission, etc.

Thanks. Style of driving quick), but without fanaticism! But I think that 19 liters on 100 kilometers it all the same are a lot of. You had earlier EDGE 2008 AWD? What octane number your fuel 92,95,98 had? What expenditure at your new EDGE? ! Thank you!

Octane used: 87, regular unleaded, under the AKI rating (used in North America, Australia, New Zealand); I believe the equivalent for your area would be 92 under the RON rating.

 

Not sure what you mean by "expenditure", but guessing you're asking for the fuel mileage on my 2011. If so, I am now getting 12.5-13 L/100km city driving and 8 for highway, if I drive no faster than 90-100 km/h, which I normally don't.

Hello. Yes, you correctly understood. Thanks for the response. What engine at you is set 3.5 or another?

Whether you change the fuel filter? Thanks.

3.5; I have only 25000km on my 2011, so, no, I haven't changed the fuel filter.
