Winter gas milage
 
Anyone notice change in gas consumption when the temperture drop? I notice the milage dropped from 25mpg to 23.5mpg. Not sure it is because of the weather or the snow tires. Or some else!

Mine had been dropping, but the average took a big jump back up when I mounted the winter tires. The Goodyear Efficient Grips are suppose to offer low rolling resistance, but I wasn't doing well with them at all. My Pilot PA3 winters are also classified as LRR, and thus far have proved to be both more comfortable and more efficient. The former I was expecting (17" non-runflat), but the latter I was not.

Colder weather and dryer air lead to increased combustion efficiency.

However, additives are added to gasoline in the winter and typically MPGs go down.
