Thanks for replying.
My distances haven't changed- Mostly running errands and shopping in New Orleans. I work 130mi away so the highway pattern (cruising 68-78mph) is the same too. Since posting I checked my tires which say a max of 44psi and I only have 32-33psi but that is also what I had when I was getting 27mpg. I have been running the AC a little bit more but I was also using it with the 27mpg. Can AC usage drop efficiency by 7mpg?
