    Understood, I grew up in Oklahoma. Just I don't have a correction factor for AC because there are too many variables:
    1. Recirculate is more efficient than pass-through as this minimizes the amount of air being cooled.
    2. Warmer internal cabin is more efficient because it reduces the compressor runs. Driving solo in short sleeve shirts with top vents pointed at me, I can handle 78F.
    3. Higher humidity is going to be worse because of the energy is needed to condense the water.
    Let me suggest waiting until October/November cooler temperatures when you can drive without AC and re-run the benchmark. Alternatively, sometimes very late, after midnight, it might be cool enough to re-run the benchmark. I live in north Alabama and I've done this many times in the past to find tolerable temperatures and less traffic. Perhaps you might try a fishing trip to the Gulf and leave at 3 AM?

    GOOD LUCK!

    Sea-sickness can be defined as having two distinct phases: (1) You think you are going to die! (2) You hope you are going to die! :eek:

    My only problem with sea-sickness used to be in having to stand extra watches because of the number of my shipmates who were TANGO-UNIFOrM.
    Riding out rough weather is really really FUN................for about 8 hours.
    Then?
    You want to do silly things like eat, bathe, and sleep.
    You find that walking on both decks and bulkheads, dodging moving objects, and having to hold on to fixed objects all of the time to stay moderately upright loses some of its novelty.
    Add the really, really, crappy weather that's usually present during rough seas and desk jobs start to look a little better after a few days. :)

    Tire pressure is an even 38 psi on all four. I have driven the car around town, parked, walked around and touched each rotor. All rotors felt the same temperature wise and I could keep my finger on them without getting hurt.

    bump the front up 2 psi. and drive it on the highway for 10 miles, then touch the rotors.

    I am in Houston but see no real problems with gas mileage with AC on the whole time. I have a 2014 that I drove regularly all summer got 50 mpg going 70+ mph on the freeways. I could get near 60 mpg if I kept it under 60mph regularly, but Houston is too big for slow driving.
    I just picked up a 2010 with 164K miles on the clock and got 44mpg with some of the same driving on my 1st tank, but had windows open due to mold or some other smell. I will observe the mileage now on the 2010, since I have taken care of the odor and can drive with the windows closed.

    After checking the car out of ther weekend, I found the front tires to be just under 25 Lb pressure. I have aired it up to just over 35Lb. It should be easier to get 50+ for this week's commute.
