Trying not to go above 4k rpm while under 1000 miles, but it is just too fun not to sometimes

Seems like the gas mileage is getting better as I break the car in. Was only getting 15mpg for the first few days I drove it, now it wont go below 21 on average between my city and highway driving. I did test it the other night on the way home from work with moderate traffic on the freeway, I reset the trip just as I was getting on the onramp. Being as light on the gas as I could and keeping it in 5th gear most of the time I inched it up to 32.5mpg before I had to get off the freeway and go back to city driving.

I am really hoping my average between city/highway gets up to the 25-30mpg range for the life of the car, but time will tell as I break it in.
At 13k miles I'm getting a solid 27mpg of mostly highway (pure highway trips are 30mpg on average). It will come up.

Also, your car does A LOT of idling or the dealer miles are super break in. My MPG was low at first, but after about 1000 miles I reset all the meters and instantly got at least a 3mpg bump. I think if you reset it you will get a much more true reflection of your real and current efficiency.
