Added benefit from HFC's...

If you can't get past the teens...maybe you should let your car warm up for 10-15 minutes before driving. Its better for the car that way anyway

Actually, it's worse for the car to sit for 20 minutes ice-cold and idling than it is to be driven conservatively. Conservative driving when cold will warm the engine faster and lead to less wear overall. Been at this winter driving for some time now

I don't recall saying 20 minutes. I said 10-15... And if letting your car warm up for a few minutes before driving it is so bad for the car..why are you not supposed to drive it after first turning it on in the cold weather?!! Belts squeak when the car is cold....

Not quite sure how having your car sitting while running for 15 minutes is going to improve your gas mileage.

Frost how the hell do you get 25mpg in traffic

OP how the hell do you get 30mpg period, lemme guess cruise control, all highway, flat land the whole way.

Constant speed, flat highway, yep cruise control, cool temps, light traffic, pretty much all fell into place on that fateful day. When I drove to Ohio from Texas a few months back, my average for the entire trip was 22mpg, to include city driving, I dont drive like a grandma either, but I try to stay in a high gear when possible.
