mpg cold vs warm weather
 

Here in ct my 96 civic dx auto got 25 mpg when it was cold out which I thought was terrible. Now its like 50 degrees out and this last tank I got 33.5 mpg. I know mpg is better in the warmer weather but dosent that sound like alot? Its not even all that warm out yet! I hear its usualy about a 10% difference but thats way more.

I was wondering what everyone elses mpg differences are cold vs warm weather?

It's hard for me to say because in the fall-spring I'm on campus and i get city mileage + when there's snow on the ground, there's always some wheel spin to get going in chicago. In the summer, I get almost all highway mile going to work. Naturally, my mpg are higher during the summer because of this (i got 40 once! :D, usually high 30's in the summer).

BUT... in the winter, when the air is colder, it is denser. that means my civic is sucking in more air (kind of like a naturally boost). wouldn't this give me more power AND better mpg? maybe i'm missing something.

yea, in my '02 civic i get about 28-30 mpg city and highway combined driving. once it gets warm, i usually get around 31-34 mpg.

i usually lose 8-10mpg highway miles in the winter.
