21 MPG



  • Having clocked my mx over a full tank, I only managed 21.8!
    any ideas on what I can do to increase my MPG?
    Recently Serviced, good tyre pressures, sensible driving.

    did you know the lambda sensors are a servicable item too there only good for 5 years..

    edit.. in addition if your running rich this will cause the cat to over heat also and add to the issue of comsumption, a good admission of this is your emmision test results…are they higher than last years results...

    the life expectancy of a cat should be the life of the car, however this is reduced due to the level of tune if done, maintence of the engine which it has or has not had and servicable parts replaced



  • just dug out my old tests for a ref check johnny and mine went up slightly last year from the previous two years but this i believe was down to the rear box needing replacing..
    I have now replaced the rear box and fitted new lambda sensors which i could feel the difference in tune of the car so looking forward to mot time and retest..etc…



  • cheers
    many thanks



  • from 20 quid i got 60 miles : (



  • 20 quid for 60 miles..shit i get double that out of the 1.6!"
    diagnostic check for faulty sensors/ECU? like temp sensor?



  • I got 28 ish from my 1.8, 34 from my 1.6 auto, 21 from my ZE if I treat it nice… If i'm dragging it then its in single figures.



  • Hi there,

    New member! I had a few concerns about my MPG, my mx3 1.8 is only a month old (to me at least) but just got 31.1 out of the last tank. I used the expensive stuff mind!



  • Unfortunatly thats about right i recon, its so hard to resist putting your foot down and hearing it sing :lol:



  • ZE + MSnS + long trip = 33/34mpg :D



  • ze on 1.8 ecu not chiped 15 mpg :(
