One thing to keep in mind. When manufacturers state fuel range they are not running the tank empty to get that. There will probably be a couple gallons left so I would say middle of the road average will be 32mpg leaving about 2 gallons left to get to the next fuel stop. Then probably 10-15% more all highway so 35-37mpg all hwy.
Besides the fuel economy anyone have a guess why it would require 91 octane fuel? I'm thinking at 173 hp from 2.4L that's probably overkill, I seriously doubt the engine is tuned aggressively enough to need premium.
That's my point, why 91+? Seems to me at that power level they could get away with 87...
