Poor MPG

[chris g 0]

I seem to be getting really bad MPG from my 2.0 16v, around 27mpg.

 

I do quite a few miles a week , some of which is around town, i don't drive the car all hard very often and about 70 - 80% of my driving is on the dual carrigeway cruising at around 65 - 75 mph.

 

I also have a problem with the car idling quite high, between 1000 and 2000 rpm depending on how it feels and I wondered if it is connected.

 

If I reset the MFA while I am driving on the dual carriageway it seems to be really good (40 mpg constant) it just seems to drop very raspidly when driving around town.

 

Is the MPG I'm getting how it should be or do you have any suggestions to what could be causing it?

the mfa shows an 'average' mpg based on manifold pressure and distance travelled, its not exact. being an average would explain why its better if you reset it on the move, and the drop afterwards...

 

and afaik 27 isnt that bad anyway mate. as for the idle, im sure someone will be able to help you with that soon :D .meanwhile use the search function at the top, this subjects been covered many times. Andy

27 mpg on 2.0 16v is ok.

I am getting 13-18 mpg on mine !!! :(

thats about what i used to get on my 16v, but if you work it out by filling the tank to the top, reset mode 2 on the MFA, drive it for a few days, fill to the top again and take note of how much fuel you put in you can work out how much fuel you've used over the miles now showing in mode 2, should give you more accurate results.

I've just done that, MFA was saying 27, but it worked out to be 26.5 which is quite accurate really. Oh well, i'll just have to avoid around town driving as much as possible!!!

 

Cheers guys
