Best MPG's will be found when the ambient air temp is right in the middle of winter low and summer highs.If it's cold where you're at I wouldn't think that's too bad for break-in mpg. Either way it should slightly improve with more miles, mine did.
Engines run highest Ef with colder temps, but frictional losses will take net lower.
Engines will run lowest Ef with hotter temps, but that will offset the lower frictional losses and thus take net lower.
The balance will be about the middle of those two. But this is per location, hence why comparing MPG's of same vehicle that drives in different locations is very not valid. The driver in say Chicago needs to compare with other drivers in Chicago.
