Hello, I recently purchased a new '06 RIO5, and despite almost all highway driving and the same style of driving that used to get me 30+ MPG in a larger, heavier car, I'm getting only around 26-27mpg in my first tanks full in the new smaller, lighter Rio5.
My question is, do Kias usually have a "break in" period on their engines where I might expect the MPG to improve as I put on some more mileage?
Also, while I have your kind attention, does nayone know where I can find a radio wiring harness for the '06 Rio5? None of the local shops or even the mega stores carry it yet.
-Thanks in advance!
