Not too bad. I was averaging 17.5mpg a tank combined and I am getting about 16mpg now. It's a trade off. I drive the truck a lot for work and get reimbursed for milage, so it kind of evens out.
Unfortunately, I wasn't in my truck. I was driving a silver X3 that a relative owns. She'd just flown back from Germany and needed someone to drive for her, and she didn't want to ride in the truck. Spent more time in the car than my brother's hooding.
