tires are at 32psi all around
weather is pretty strong out on the open road
the xfe doesnt go straight very easily with the winds
weather is very damp/humid 80-85 in the morning
no defrost but ac is on -
its been on everyday -
so that is not the variable in terms of going from 38 to 31
i thought u get more mpg with cooler air
the air is more dense, and more o2 molecules in the air
air + gas = boom
more air = less gas needed
