This is more than an annoyance if you're one of the people who didn't pay enough attention to tank size, and are stuck with a 23 gallon tank LOL. I didn't have this problem with my truck for the first year I owned it. Now I'm seeing it happen more and more often. I finally narrowed it down to specific gas stations that have recently replaced their fuel nozzles. There is one CFN station I can go to that this doesn't happen. They haven't replaced their nozzles for a long time. I know this isn't a gauge issue. When I fill up at that CFN station, my gauge reads full and my DTE reads 340 miles. When I fill up anywhere else I've tried, my gauge reads just under full and my DTE reads 305 miles. I'll probably end up going to my dealer for this, but for now I'm living with it.
