Low Mpg 728I

[maverp1]

Hi all

I am getting a reading of 15.2-15.4 on my read out for average mpg from my 728i ,I do a lot of short trips as I work very local to where I live, would you say that this is about correct or a little low if so what would you advise to look at first as a causes for the consumption. I am planning on taking it out on a bit of a run Saturday so what sort of figures should I expect on that , all help much appreciated

Cheers Paul

hey Paul,

My 728i averages 22mpg and i live in central london. Used to get a good 35 on the motorway which was nice though

Reset your MPG comp and take her on a long run

I'm hoping an automatic 330i would achieve better than that... My daily commute's a combination of A-road, motorway and city driving. My last car (R56 MINI Cooper S) averaged just over 35mpg all said and done, so as long as I can stay near 30mpg that'll be okay.

Thanks for your help in the middle of checking the read out accuracy if this proves correct will be going down the route of changing plugs and cam/crank sensors

that is very low. I drive a mix of motorway and crawling round London. I get about 30-32 on a run, maybe more and around 22-24 around town.

here's my fuel comp during a long m-way run a while back

In case it's not obvious, I reset the trip meter when I fuelled up.

And I'm not a Sunday driver by the way!!!!! But of course always legal... ;)
