It is higher than this.. but for discussion sake, 75% highway - One would think that the MPG should be higher than this, I do!!!
What you're doing on the highway is probably more important than just the amount of time spent there. Are you able to get into the fast lane and just cruise, or are you constantly slowing down and speeding up due to traffic.
I drive faster on the highway so I can sit in the left lane, and I pay for it with the mileage going down, but if I drove slower, I'd spend more time adjusting my speed and probably do worse MPG-wise. If you want super awesome highway MPG, set the cruise for 5 under and sit in the right lane...but ain't nobody got time for that.
