    Do you get better or worse gas mileage with winter fuel or summer? Just curious.

    Depends on where you live, and what the regulations are for RVP and ethanol. In CO, Summer is mandated to have lower RVP (7.6). Winter is higher RVP (9.8 I think). Neither of which have a distinct effect regarding MPG, but do affect the resistance to burning and horsepower. The killer in CO is that the front range of CO is mandated to have ethanol, at 10% per gallon. Well, ethanol has roughly 33% less BTU content, resulting in a certain loss of fuel economy, and very hard on any vehicle, lawnmower, etc. If you can buy non-ethanol fuel, do it. Ethanol bad, clear fuel good.

    Here in northern New Mexico, I get about 1-1.5 mpgs less in the winter.

    Go up an octane grade in winter to offset the blend.

    More drag in cooler temps. Check your tire pressure as that will be a few psi lower once the temp drops.

    doesn't really matter to us up here in the northern tier (ND). using remote start kills mpg no matter what. during a hard cold snap and using remote start, think the tank avg dropped to 7 mpg once.

    Don't forget to swap out summer air for winter air in your tires for better MPG
