Hello Edge folks: Happy Holiday Season! First of, I'd like to say that I did my search work but couldn't find what I am looking for, maybe because it hasn't been posted yet (which I doubt it), but probably because I didn't managed my search properly. My apologies before hand if the latter is the case. But if so, please feel free to forward me or send me in the right direction. As the tittle suggests, I'm going to ask a few questions about fuel consumption, specifically liters/100 Km (the Canadian or metric system) or the equivalent GPM (the American or imperial system). The objective and result are the same (just a conversion factor). As shown in my profile, I have a 2011 SEL (FWD) with about 186000 Km (116000 miles) in it. I may have not paid enough attention since I bought it over two years ago, but now finances are shrinking, and the good environment as well So, lately (don't know since when but many months ago if not over a year by now) my car fuel consumption is not going below 14L/100Km (or above the equivalent 16.8 mpg). When I cross reference the specifications for this car in different websites, most of them agree to state the worse (city driving conditions) performance of this car new should be around 11L/100Km (or 21mpg). Even when I have been driving mostly on the HW, I can't get below 14L/100Km. i know the car is already over 8 years old, but I want to start with two main questions: 1.- Is that claim (11L/100Km or 21mpg) true? Was it ever achievable with this car? I know the VW got nailed for misleading the public on this subject but I never heard of a similar issue with Ford. 2.- IF this claim is true, what maintenance, replacement or repair should I do to improve the fuel consumption/economy/efficiency in this car? Now, related to my second question, please, I would like to hear suggestions/solutions from the most effective ones down. What I mean is, a cold air intake may improve (or may not, depending on other things); a K&N filter may improve (but may not, depending on other things). Basically, I would like to start from basic maintenance things I should change/replace/repair which are known to dramatically improve fuel consumption/economy/efficiency, if you folks don't mind, please. Then we can go to the "fine tune" And of course, feel free to ask any questions you may have. I'm basing my questions on highway driving conditions during summer time (Canadian city driving conditions during Canadian winter time throws ALL READINGS out! lol Thanks so much in advance.
