So as most people in the great (not white yet) north know, cold temperatures and winter gas kill mileage. i have a 2009 honda civic ex coupe with the 5spd manual transmission. my drive is 42 miles each way - about 35 miles of which is highway. in the summer i average 39-41 mpg, but in the winter i average 36-37. Losing that mileage stinks. I have installed a partial upper and lower grill block this year. I however don't want to go to he pain of a block heater.

Any other tips or mods i could do to help me out in the winter?

Thanks,
Brandon
