Yes - snow tires! I forgot them on the list.
LED lights, racing sailboats, Gevulde speculaas, windmill cookies, remote control airplanes, Old Gouda cheese, salty licorice, king mints, and also those big dry melba toast things, rusks, shortbread, fish & chips shake, narcotics, narcotics laws, homeowner's insurance, stolen pot, back to bush planes, & finally back to engine block heaters! If I overlooked a few topics, I apologize.
I traveled (a little more than 6 hours) from SW Wisconsin to Green Bay & back home again (Christmas gathering for relatives) today. My driving is a mix of rural hill roads for the first 45 minutes or so, about 1.5 hours of two lane state highways, and about 1 hour of 4-6 lane interstate (Oshkosh, Fox Valley area, Neenah, Menasha, Appleton, Green Bay). Most of the two lane highways I was pushing it to 60-65 mph. Once I hit Oshkosh to Green Bay, I was going 70-80 mph for the remaining part.
I have Nokian Nordman 7 snow tires up front & Federal SS657 on the rear. I keep my tires at approximately 40 psi. I had filled my gas tank the day before this trip. Thus, I had some local mileage on my car. Today was quite mild (mid-40s) for Wisconsin, & the wind wasn't bad. I filled back up tonight before getting home. My last bar had just started flashing.
Trip odometer was 323.2 miles & it took 6.974 gallons to fill up my car. MPG = 46.34
I do this trip quite often, because my parents live north of Green Bay. I seldom every get below 40 mpg driving anywhere any time of the year with my Mirage, but mild temperatures & lack of wind today made me get similar to my summer time numbers for this trip.
It's the cold weather (low temperatures) & strong winds that seem to zap my mpg the most. In my opinion, the snow tires & winter fuel aren't the biggest factor. Snow tires plowing through snow or slush, however, is a different story.
I have noticed good days, and bad days, with winter driving and my own 2014 Mirage's fuel economy. I find some gas seems to last longer than other brands as well.
Another factor drinking gas for me is.. I drive in a lower gear more readily in the winter. Like for the added traction I get with quicker torque and throttle response. Does drink more gas the higher those rpm's go.
View my fuel log 214 Mirage ES 1.2 manual: 39.8 mpg (US) ... 16.9 km/L ... 5.9 L/100 km ... 47.8 mpg (Imp)
AtomicPunk : thank you for the actual LOL. And to Mark for the summary.
