We Reviewed Eco OBD2 Fuel Saver -This is What we Think about It

Whether it’s called EcoBox, EcoTune, EcoFuel, Effuel, or EcoHack, who doesn’t like the idea of a product that saves fuel? Not you or us. This is why we bought and reviewed the plug and drive fuel saver known as Eco OBD2.

Unboxing:

We ordered the product from ordereffuel.com and it came in approximately two weeks. First of all, the website promised us that our fuel consumption would be reduced by 35% but when the package arrived, we were surprised to see the words 15% save fuel.

What happened to the 35% we were promised earlier?

Anyway saving 15% fuel is not bad. At least we get to use the money to buy some pizza. Well, lets get to the real testing & driving.

Testing & Driving:

We tested the Eco OBD2 in a 2008 Prius. Since it claims to save 15% fuel, we expected to lost about 3mpg for a 150 miles drive.

Sadly, it didn’t work for us. We lost about 6 mpg, even though we didn’t drive up to150 miles. 

 So we decided to try it on a 2003 Ford Expedition as well. The little light keeps flashing, so we don’t know if that means it can’t communicate with the 2003 Ford or not.

Our Auto Mechanic laughed when we showed it to her.

Eco OBD2 Fuel Saver: Pros & Cons

Sorry, there’s nothing to like about this product. It is just a piece of junk that we’ve seen recycled many times. In fact, when you check Alibaba or Aliexpress you’d see that 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.

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 doesn’t re-align the molecular structure of the fuel before it reaches the fuel injectors. It is just an expensive LED flasher.  

Does Eco OBD2 Really Reduce Fuel Consumption?

Ignore the positive reviews online, OBD2 units do not work. When we opened and dissected one, we discovered it is just pure 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.

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.
