Hi all! Well I was hoping not to have to make a thread like this, but I need some advice on poor fuel consumption. I bought a 2004 82,000 mile 2.4 Automatic 3 weeks ago and have been experiencing very bad fuel consumption figures. This is despite a fulls service having been carried out and me driving in semi-grandpa mode. This was one of my biggest concerns before buying and I would really aperreciate some advice.
1st Fill up - £30 - 90 Miles so @ 99p per litre = 6.66 Gallons = 13.6 MPG
Some of this mileage was before the service and I ***ume that the car was left running throughout the service. Also most of the driving was also in bad traffic
2nd Fill up - £30 - 120 miles - 120 miles @ £1.06 per litre = 6.22 gallons = 19.29 MPG
This was particularly worrying as this was after the service where air/pollen/fuel filters were changed e.t.c, and without much traffic at all and 40% motorway or dual carriageway driving.
I measured the MPG by zeroing the mileage when the petrol light came on,then filling up with £30 of petrol and waiting until the petrol light came on to measure the MPG.
I have been reading up and have the following ideas of what to check:
- Clean MAF sensor & EGR
- Calipers (though I think they should have been checked already)
- UN-metred air in the system
- 02 Sensor
- Clean throttle body/sensor
- Wheel Allignment
- Tune up
- Pipes for damage
- Air filter connection hoses.
I put a bottle of cataclean to clean fuel injectors so will see if that makes any difference.
Unfortunately, I am not very mechanically minded so would have to get a mechanic to perform any of the above. Are these the correct things to check and have I missed anything important?
