So I lost apx. 1 MPG in mileage this winter but I get 5 MPG back? Dang, where do I sign up for that? After 10 years I should be up to 70 MPG!!
Much of the mileage difference is cooler denser air = more resistance, wet roads = more resistance, winter blend fuels = worse mileage. So IMO, I possibly lost 1/2 mpg due to longer warmup times.
