    Have your engine and inverter antifreeze coolant changed. I tested mine and the inverters ph was getting high. Sorry, I forget the number. After flushing and refilling, my mileage did go up. Guessing that the coolant lubricants and the thermal transfer properties helped regain my gas mileage. I changed mine near 100k.

    the coolant shouldn't have anything to do with mpg.
