What we Like about Ecobox Fuel Saver

  • It’s easy to install

What we don’t like

  • Ecobox is just a piece of junk that we’ve seen recycled many times. As of 2017 this same product entered the market. It was ‘Ecofuel’, and similar to Ecobox it didn’t do zilch.
  • What these sites do is buy hundreds (if not thousands) of generic OBD2 fuel savers from China for $3 a piece (or less,) design their own packaging, and re-sell it to you for $40 a piece.
  • Although they’re sold under different names, with unique packaging and have fancy websites, these OBD2 fuel savers are all scams and should be avoided at all costs. See Ecotune, Eco Obd2.

Does Ecobox Really Reduce Fuel Consumption?

Ignore the positive reviews online, Ecobox does not work. When we opened and dissected it, we discovered it is just a junk. First of all, it doesn’t have any drive for CAM.

Secondly, the unit DO NOT have any connection to OBD communication. Only what is connected is Power for the flasher to flash. In order to do what these companies claim, you would have to redesign the car. The major parts of how much fuel any car uses are: vehicle weight, tire size, rolling resistance, friction in moving parts, number of moving parts in the driveline, etc. There is nothing plug and play that can alter these basic factors.


Just like Ecochip, Ecobox is not a legit fuel saver. It doesn’t affect fuel consumption in any way. Let’s be realistic – it was only made for profits. It is simply a magnet that you fasten to your fuel line. It is just an expensive LED flasher. You wouldn’t reduce fuel cost when you use it.  

If you’re thinking of reducing fuel consumption, Energy.GOV has a list of helpful fuel-saving tips including combining trips, stripping your car of unnecessary weight, keeping your car in tip-top shape, and how to avoid aggressive driving.

By themselves, each tip might not seem like a lot but, combined over time, the fuel-savings make a difference.
