Can't speak for MO, but have noticed a slight dip in mileage here. Now that the colder temps are upon us, I'll bet they've already started formulating winter gas. God knows since it all comes out of the same pipelines, it's probably in many of our tanks in the snow belt already. :irate:My gas mileage the last 2 tanks has dropped noticably. With less use of A/C and not having to run defrost or floor at all, i expected to improve slightly, not decrease. Anyone else notice a change in the Missouri/Kansas areas?
In cold weather climates, higher concentrations of ethanol and other additives are blended in to keep the fuel from freezing.i just learned of the different formulas recently. what is the difference?
