I must have gotten a fresh tank of the non winter blend (less oxygenated) gas from Costco because on that tankful I'm up to 20.2 from 18.8, with the same (as much as possible) driving speed and route (highway @75+) Also they were back to back fill ups from the same Costco about 7 days apart fwiw. I'm also calculating based on the DIC and hand calc gals divided by the odometer miles.
