My 2010 F150 FX4 has 192,000 miles and I still get over 500 miles a tank.
And that’s in Houston, running A/C essentially 348 days a year.
The Denali A/C has a mind of it’s own
the compressor will run even in depths of the Chicago the winter
I think it’s for the defroster but it seems to know what it’s doing
it’s always VERY comfortable after only a few minutes
