I’m the org. Owner of a 2012 ex-l awd. I used to get 18-20mpg around town, now I’m at about 15. I have 118K on it, all maintenance done, timing belt, plugs, ect... all changed at 105K. I’m in central Wisconsin, so we have cold weather and winter gas, which gets you worse millage, but it’s never been this bad. Is there anything else I should consider? Would my O2 sensors be starting to go bad, but not to where they throw a code yet? Thanks for any input.
