I recently purchased my 2008 HCH2 and I am loving it! When I purchased it, I didn't know the specifics about hypermileage and maximizing FE. With that being said I also purchased accessories for the Civic and now I am concerned that will take a hit on my FE. Speficially, I purchased the fog lights, bass package and the interior illumination. Does anyone have an idea about how much these accessories will effect FE? Thank you very much!
