    I haven't hit 7.9 since the summer of '12

    Hopefully this year will be better.

    I don't know if it's a placebo effect, but I've been averaging about 7.5L/100km since I switched to Esso in April 0_o

    I get similar fuel economy with my stock 2010. I don't drive it hard. Have the RX-8 for that purpose.

    So I drive a manual 2012 mz3 GS Skyactiv, I average 7.0 litres/100kms, I use 91 octane gas and mainly do country driving (80km an hour zones) very little city. My best was 6.16 litres per 100 kms, and my worst was 8.59/100kms... all my info is kept in the gas cubby app. Been driving for about 8 months with it now!

    Why are you wasting $ on 91 octane fuel when the motor is designed for 87?

    Now that my summers are back on and shed almost 7lbs per tire, I'm back down to the low 7's/100km combo of hwy, city and traffic with my 2.0L MZR + 5MT and using 87 octane from ESSO or Shell.

    I'm normally 7.5 - 10L/100km depending on traffic and my left foot.

    Hi all, I got a 2010 Mazda 3 2.5L. I bought it used around 4 months ago. Everything is superb about it except for the fuel economy. I been driving everyday for the pass like 4 months and on my display it shows Average fuel Economy of 16.2-16.3L/100KM. After reading through all the posts on this thread my numbers definitely not good and most likely something is wrong. I do over 95% city driving and seldom go on the highway. Can you guys give me some suggestion what I should and what may be wrong with it?

    My car is missing the undertray cover underneath the engine(when I bought it), should this be a concern and could this be the cause of the extra fuel consumption? thanks in advance for help!

    You need to replace that tray. Yes it is for aerodynamic reasons but it stops all the road dirt and salt from ending up in your engine bay. If you do 95% city driving I think that the fuel economy you're seeing is to be expected. Perhaps you should have got then 2.0L SkyActiv as you don't use the 2.5's extra power often.

    Maybe I should have gone for the 2.0L but I like the extra punch with the 2.5. Couple of the posters here also got the 2.5L but they're getting between 8.3 to 11L/100km...a missing undertray wouldn't cause0 that big of a different in fuel consumption? It's more or less consuming twice as much.

    A lot of it has to do with driving habits

    A heavy foot at the lights (not necessarily speeding), long idle, and even the winter fuel - all play a part in fuel consumption.

    Try keeping it under 2,000 RPM and see if there is an improvement.
