Yeah I'm really starting to think the car itself it fine. If I put in in Drive, with Snow/ETC mode on, and let it roll off on a nice flat road it goes up to about 21 mpg. I got about 14 mpg on the first day after I last filled up, which was slightly less congested than usual and I had some nice stretches of cruising. It's also ridiculously cold and slippery and I only have all-year tires (deep threading but no dobs or spikes).
I'm gonna wait and see how it goes in the summer when I'll be doing a bit longer drives with (hopefully) less traffic.

Hi just wanted to confirm if your mileage improved after changing the A/F Sensor?
I'm thinking of changing one of mine as I have had a CEL pointing towards the passenger side one, not the front one.
My mileage is about 14-15 MPG where 3 years ago it was 20-21 MPG.
Thanks
