I went across Oklahoma last weekend from east to west up and down hills and got 16.5mpg at 75-80 with the a/c on. For the return trip I stopped at a Shell station and filled up. The Shell gas, I have heard and now verified, gets a little better mileage. In this case it was 19.3mpg doing 70-75 with minimal a/c use where I normally would get 17.5-18.0 under the same conditions. When I use the Walmart gas here in Tulsa I consistantly get 1mpg less every time when compared to the gas at the Quick Trip station. These aren't just one off numbers, these are regularly repeated results for me.
