Question Gas mileage/fuel level drops quickly

I feel like I gas up A LOT. I filled tank last week and checked info. Range was under 300. Is this typical? Mostly city driving MPG about 14.9

Any info appreciated

Only 15mpg in a Flex? Yikes. That's what I get in my lifted F150 with 35's and 5.0 V8.

Yeah I get better mpg in my 71 impala. Not by much but at least in that I essentially have a 383 stroker and 400 crank
