Hi, apologies if this topic was already posted as I didn't see it on a search, I have an 06 IS 250 and have noticed a considerable drop of MPG for this past winter. My previous MPG was ~25.5 and have now been driving at ~21 MPG per round of fueling.
There are now 62k miles, but have brand new tires and keep up the 5k maintenance like clockworks. Has anyone noticed an MPG reduction reduction during the winter months, especially in a cold weather climate like New York?
Any input would be appreciated.
thanks,
Justin
