Well this is my first fill up with the new truck. Although I am happy with the overall MPG ,I am not happy how off the dash is. Here is the results. Dash was saying 30mpg. Hand calculated was 26.2 which is great in my opinion. However I do wish the dash was closer. As far as my commute I have a 120 mile round trip everyday. 90% is all highway. I drive at about average 71mph but I will say for some reason the dash will read higher mpg if I do 75. So maybe my truck has a sweet spot. I am excited to get the 26.2 ,can’t wait to see what the future holds. Here is the picture of the dash and my fuel receipt so you all can see.
