Discuss these mods and suggest new ones in the forum. Below is a list of well understood mods you can do to your vehicle to squeeze more distance from each drop of fuel. They range from mild to wild, free to expensive. Some admittedly split hairs, while others can make a significant fuel economy difference. EcoModder members have done most, if not all of these. You'll note a distinct lack of "magic bullet" or "fringe" category modifications here (particularly additives and infomercial gadgets). To understand why they're omitted, spend some time in our "Unicorn Corral". Disclaimer: some of the modifications on this list may be illegal in some areas. Some could alter your vehicle's driveability or handling characteristics. Others may be potentially damaging, depending on the skill of the mechanic and the ability of the driver to monitor his/her vehicle. So don't be stupid! Make safety your first priority. > Also see our 100+ Hypermiling / EcoDriving tips
