66 vehicle mods for better fuel economy

[AVANTI R5]

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 at this site: Fuel saving - a professional engineer's view.

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.

Yup, cuz that's gonna last for a long while


That was one of the worst/unsafe articles I've read in a long time.

Most of them sound like you are going to spend $500 modding your car to save $2 at the pump while making your car look stupid, or less safe. Yea lets remove our windshield wipers!

Here's my list:
--put a few extra psi in each tire
--slow down
--remove extra junk from trunk and/or roof

It's not a matter of slowing down even. You can drive fast, it's how you get to that speed and how well can you maintain it witout excessive slowing down and hard acceleration that matters.
you don't have to be the slowest car on the road in order to have great fuel economy.

I'm able to hit 36mpg around suburbs in my MINI if i drive like grandma getting to the 50 or 55mph of cruising speed.
If I drive the MINI like I used to drive my WRX, while still doing 50, 55 or 45mph, I will get about 31mpg

That was sort of a stupid read, some of those 'tips' are insanely ridiculous. ...shave your door handles although you will be ticketed by law enforcement and potentially trapped in your car when things go bad.

I found this to work best when gas prices were sky high

Ride a motorcycle.

[linus011]

Even better, ride a bicycle.

[whoosh]

make the wife walk

[Mike Wevrick]

^^You jest, but mine takes the commuter rail; definitely better than driving to work.

All of these matter. Doing 60 instead of 70 on the highway definitely burns less gas.

Even better, ride a bicycle.

I do this (or walk) if I am going somewhere in town.

I also try to "chain" trips eg if I need to go to a store 10 miles away I will also try to hit a bunch of other stores in the same area that I might need something from.

One more: carpool. I used to do it for work and now do it was much as possible for weekend canoe trips.

I'm terrible.


I usually remove psi when off-roading

Yeah, no

I have a spare tyre and roof basket up there
