A bit excessive

A bit excessive
So Ive been doing a lot of highway driving (usual around 60-65 mph) and Ive been finding that H3 has been using a lot more fuel than normal.
I filled up (had a bit under quarter tank) and I put in 70 litres (18.42 gallon). I check the mileage (I reset it every time) and it was 215 miles. By my calculation that is just around 11 mpg.
That cant be right. I remember I used to get a bit over 20 mpg. Or did i just dream that.
I did a search and noticed a few posts that are related to engine head. I got 39000 miles on it, and its an 06 (one of the troubled head ones), but I am not showing any head issues at this point.
The only mod is that I put in K&N filter.
Suggestions?

Not every time, but almost always if you have the head valve issue you would have a CEL and you would notice a very rough idle.
Heve you checked your brakes? A stiff corroded caliper could drag a pad and would pull down your MPG.
You might have been dreaming about 20mpg, at the 65 mph range I can get 19 in warm weather. Today it is 15F now and 19 is not gonna happen in that.

There will be days when the weather sucks: cold blustery wind head on, and driving conditions are not ideal: many large hills, etc... when we get less than stellar mpg, but you should be doing better than 11-12 for sure at 60-70MPH.

I gave up with the whole milage thing. I'm driving a vehicle with the aerodynamic properties of a 4x8 sheet of plywood with a weak 5 cylinder engine - good milage ain't gonna happen!! My 4.4 BMW X5 is the same - huge performance engine with not the best aero package! If I wanted good milage and it was a real concern I wouldn't have bought these vehicles. That being said - I bought these cars for their performance, looks, and comfort - I wouldn't get rid of either one!
