I would start with the coolant system. Make sure there’s no signs of belt slippage (bad tensioner).
Plugged radiator/CAC/AC condenser. Water pump (bad impeller). Faulty coolant sensor reading incorrectly. If the engine fan is on alot/all the time it will really affect your mileage. Also don’t forget to inspect your brakes to make sure they’re not dragging(bad slack adj.) or an air valve on the parking brake side leaking causing them to drag. All that extra heat going into your coolant system costs $$$. Good luck.
