Okay all you math wizzes, I just did a 136 mile round trip on a combination of highway (55mph) and back roads (45mph). I filled up before I left and when I got back, I used 9 gallons. That comes out to just over 15mpg and I am not happy with that at all. Then I started thinking about the speedo and if it was off, so I checked it with my gps and the speedo reads at just 10mph over what I am actually going. So at 55mph (spedo), I am actually going 45mph. How will that affect my above mpg numbers. I am running stock tires.
