What speed is the scangauge telling you returns the best mileage?
I have not exceeded 65 mph in the past week and half. Which is really about 63 because of tire size correction. Running 80, I must have been getting 10 mpg or worst. My tank has never stayed so full for so long.
What is the formula on actual miles driven with 285s vs stock? Is it 10% more miles than the trip odometer since the tires have a larger diameter?
i believe its 6% more
