How do you get your fuel mileage numbers? I keep track of each tank and use lie o meter as a guide. I was looking at trends today and realized that I can't seem to find an accurate way to do fuel economy. I have done the manual way of calculations only to realize that tank pressure change never comes into play nor does angle of the car. There are so many factors that are out of my control. I put almost 600 miles on vehicle over last couple of days with meter stating 26.8 with 400 miles on this tank and still 1/4 tank left so by far my best tank mileage. I have had lowest tank of 250 miles couple of months ago. EPA estimate is 17 city and hwy 25 or average of 20 which over 9000 miles is 20.1 so I am meeting those numbers. Might be better to just enjoy the vehicle for what I bought it for and fuel economy wasn't high on the list.
