      solved poor aveo fuel economy

      Sorry to post this but i solved the aveo poor fuel economy today by trading it for a 2011 Fiesta
      1.6 litre 6 spd auto epa 29/39 , edmonds has good history for this car regularly exceeding these
      numbers.

      Background
      owned a 2010 Aveo 5 LT 1.4 litre

      Figures for 22 fill ups are as follows

      mpg city/hwy
      #1. 25.7 80 20
      #2. 24.3 80 20
      #3. 24.1 80 20
      ----- increased tire pressure to 38 # --------
      added amsol to engine
      #4. 31.1 10 90
      #5. 26.3 100 0
      #6. 28.2 50 50
      ------installed k&n air filter -------
      #7. 28.4 50 40
      #8. 26.6 80 20
      #9. 29.7 25 75
      10. 25.1 90 10
      11. 27.7 40 60
      12. 25.4 50 50
      13. 27.6 60 40
      14. 23.6 90 10
      15. 25.7 90 10
      16. 24.9 90 10
      17. 26.0 70 30
      18. 24.6 60 40
      19. 30.3 20 80
      20. 20.1 100 0
      21. 25.7 30 70
      22. 30.8 5 95

      Now, this may not seem dismal until you consider the following:
      it compares poorly within its class
      when looking at city mpg i had a big problem. Although i live in a
      rural area, when i did drive in the city my mpg dropped to low
      20's. Heck people you can buy a pickup that will match city mpg
      for my aveo. If i lived in an urban area i would have traded it
      at the 3rd fill up, because my mileage would have been dismal.


      Sorry, Yep because i like the aveo "better". For me the seats are more comfortable,
      well placed armrest, killer stereo, good looks, behaves well on road and in
      city, parks good and dosen't complain about much and is economically
      priced. But, its time has come. its engine is poorly matched to a poor transmission
      manual or auto. We will see what the Sonic will look and perform like. But, for
      me i'm done with chevy.

      Test drove 2012 accent 6 speed manual 1.6 liter 15.5K varies.
      rpm is just as high on this car as the aveo, epa mpg 30/40....
      engine and transmission are very well matched. liked it
      no history on 2012 yet

      Test drove 2012 chevy cruz eco six spd maual 1.6 liter 18.5K varies.
      rpm much lower than aveo epa mpg 29/40/-52 liked it but no history
      on vehicle

      2010-2011 Fiesta 1.6 liter man or auto
      well documented with good history mpg 29+ --40+ good history
      bought at 13.2K. don't like as well as Aveo but mpg is the
      only driving force at this point and in this price range. Well documented
      city EPA mpg exceeds 29 mpg versus my Aveo at low 20's So
      "bought it". Engine rpm about 2250-2350 @60mph. Auto Transmission
      has no "torque converter" it is a dual clutch setup.
      Experts think the engine and trans. are well matched.


      enjoy

      Oh, I'm not surprised at all. As I've said repeatedly, if your driving is 100% city driving (and that is exactly our situation) it is impossible to get more than 23-24 MPG from an automatic Aveo. But so far it's been reliable and my wife loves the car (it's for her commute) so we're not about to trade it in.

      Yes, I also would like to see the results with the Ford for all city driving. I would expect the MPG might be somewhat higher, but not dramatically so.

      With the automatic it's all related to the programming for the torque converter lockup. It doesn't lockup until 45 MPH which is much later than any Japanese car. (Average speed for entering lockup mode is usually about 38-40 MPH.) When it does lockup you get 37 MPG which is wonderful. At speeds below 45 MPH you get 24 MPG which is terrible. In other words the Aveo is a pig on fuel economy when driven at below highway speeds.

      Yeah, combined.

      Those of us who do all city driving (all at speeds below 40 MPH) aren't that fortunate.

      Let me drive your ford, see how reliable it is afterwards. I promise I will baby the car, and can all but guarantee something will break. I will stick with my chevaewoo.

      I will think of a better signature later.
