Howdy everyone... i'm just starting to get into the whole hypermiling thing.

I have a 2009 honda civic EX coupe, 5 spd manual transmission. I have been averaging 37-38 mpg per tank, with a best of 40.5 mpg. my commute is 45 miles each way, with about 60% on the interstate.

Has anyone done any modifications to an 8th generation civic? i haven't been able to find any posts on here. What have people used for a grill block?

THanks,
Brandon
