there is no way you get 30 mpg. This car should expect 19-22 avg with a mix of highway and street. The best I ever got with ECO on flat highway minimal fluctuations on speed going 65mph was 25.9 over 80 miles. I actually do not think this car is capable of 30 avgs. But I could be wrong unless it was legit downhill both waysI've got other pics that show 50 miles traveled and quarter tank burned. But shows on computer I was getting like 30 something miles per gallon.
