Fuel efficiency drops when the weather gets colder but not by so much. Quote Share this post Link to post Share on other sites
Cobra348 Report post Posted December 24, 2024 As has been mentioned, tires can affect mileage. You will get the best non-Winter miles on the OEM tread. The closest mileage I've gotten with non-OEM is Goodyear ComfortDrive tires, but even then I lost a couple MPG. If you're in the cold area of the country, the gas formulas change for Winter blends. That will also screw with the mileage. Add in snow tires (if you go that way), there's more loss. Quote Share this post Link to post Share on other sites
