Hi Tdmsu:
___Oh yes, the tire pressures

At least try the MAX Sidewall pressure cold on every automobile you own. I have stretch goals so I run ~ 20% higher then MAX Sidewall. Most Consumer tires have a MAX Sidewall of 44#’s and I hope you experiment with steadily increasing pressures with a careful log of FE across the tanks as you increase it. This will definitely make a difference in your FE, that is a guarantee.
___Good Luck
