Consistently getting 29-31 in mixed metro driving before visiting this site and learning about hypermiling and ecomodding. Looking to up the FE so that I can beat the end boss.
Getting closer to 32-33 MPG on a regular basis now. All highway travels vary, but I've posted up to 38mpg, utilizing mainly DFCO coasting, engine on (it's an automatic).
Roof Caps (see thread "Acquired Pontiac Vibe Roof caps. Now what?")
Hidden Scan Gauge (see album)
Tinted windows (does that count?)
Duct taped Upper Grille Block
Garden Edging Winter Lower Grille Block
K&N Air Filter (whether it helps FE or not, it saves me from landfilling lots of throwaway filters)
LED CHM Stop Lamp (Replaced incandescents that frequently burned, likely due to rattling)
