Default 16-18 mpg 2015 F-sport

So i purchased my 2015 IS 250 F sport approx 1 year ago with 17K miles on it...when i would fill up my tank, it would tell me i had 360 miles to next fill up. I would average about 20-22 MPG.

Over the last 4-5 months, it now tells me i have 290 miles to next fill up, and I'm getting 16-18 MPG. I feel this is significantly low.

Keep in mind I'm very mindful of my car maintenance. I drive in Eco mode, i make sure tires are properly inflated, had the air filter changed few months ago...i do more highway driving than city also.

Does anybody else have this problem? I asked the dealer to check into it and they gave me the typical BS answer saying that its AWD and its just the way it is. Now i also live in NJ and i know its been super cold here, but this problem started before the cold weather, but has gotten worse. Any thoughts are much appreciated, because I'm only getting 270 miles for each tank of gas. Is this normal?

Yes it's normal depending on your commute

That's pretty low for mostly hwy driving. I would check to see if there is a vacuum leak between the air filter and the intake. Maybe something isn't connected properly. Maybe do a battery reset to clear out the old driving behavior.

Something is wrong with your car. I have a 350 that i drive around in Sport mode and completely drive like I stole it (redline everyday, get in my daily triple, etc) and I get 17 mpg. I also have a half city half hwy commute. I would get it checked out.
