I have 2300 miles on my 2019 Ltz 4x4 Silverado. The fuel range reading in the info display has always read kind of low. On a full tank best I can get is 390 miles on range but believe I am actually getting better gas mileage. Geez in my old 2008 I actually got a 450 range reading on a tank of gas and this one is supposed to be better! I plan to manually check next time I fill up. What kind of fuel range are you all getting on your new trucks after a fill up ? And I drive normal not too fast. I presume this is a 25 gallon tank. Thanks for sharing your thoughts !
