    I've been averaging about 43 mpg but lately its been around 35-37. Is the mileage weather related or maybe they've lowered the octane. Any ideas.

    Our 2011 ALWAYS gets over 50 mpg in warm weather but drops to about 46 in the cold. Then we put on studded snow tires (rims and tires weigh about the same) and then the mpg drops to 42 from worse rolling resistance. Make sure your tire pressure has not dropped too.

    Soooo...... it would be helpful to know where you live to kind of determine what we are dealing with here. (hint, hint- update your profile!)

    it's both weather, and winter formulated gas. pump up your tyres and slow down!:p
