The other day one of my friends asked me if now, with warmer weather, I see any change in fuel consumption. His ride is a 2008 Cadillac CTS 3.6 - mine 135i. My answer: no change for me, never had, summer/winter I get and avg of 9.4, mixed hwy and city. He does get a better millage now, with spring here.
So, what is your experience? And, if you do see a diff, what would you say is the reason (assuming a consistent way of driving...
)?
