Unreasonably bad mileage

So, I've got a 2000 xj, stock height, stock tire size, nothing too special about it for now, but I've been getting like 200-250 kilometres per tank so around 120-150 miles. Besides the obvious of winter gas, bad plugs, so on so forth, any ideas why my mileage is so bad? I just recently tried sea foaming it to see if it would make any difference at all. And I'm easy on the skinny pedal, hardly ever going over like 2000-2500 rpms. Just looking for some help if anyone has ideas!

Binding brakes? Seizing wheel bearing?

Got a neighbor with a overactive siphon hose?

Engine temp too low? I got a (slightly) better mpg by mounting the Original Mopar t-stat instead of a no-brand 195 t-stat that kept the temp too low.

Distance per tank has no meaning, sort of like slice per pizza. Calculate mile per gallon, or kilometers per liter. A unexplained 20-30% drop in fuel efficiency suggests faulty O2 sensors.
