We Reviewed EcoTune Plug & Drive Fuel Saver – Here’s What we think about It

Whether it’s a chip or a plug, who doesn’t like the idea of a product that saves fuel? Not you or us. This is why we bought and reviewed EcoTune fuel save also known as Eco OBD2.


We ordered the product from ecotune.luxestone.com and it came in approximately two weeks. First of all, the website promised us that our fuel consumption would be reduced by 35%. They also offered us a 59% discount. Sounds enticing right?

When the package finally arrives, we were surprised to see the words 15% save fuel. What happened to the 35% we were promised earlier? I guess its another sales trick right?

Anyway saving 15% fuel is not bad. At least we get to use the money to buy some cold ice cream. Well, lets get to the real testing & driving. We tested it in a 2008 Prius. We lost about 6 mpg, even though we didn’t drive up to150 miles. 

It didn’t work for us. It didn’t reduce any fuel consumption at all. It just kept flashing light like some night police man.

EcoTune 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. As of 2017 this same product entered the market. It was ‘Ecofuel’, and similar to EcoTune 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.

Ecotune 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 Ecotune Plug & Drive OBD2 unit, 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.

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.


  1. Thanks Dani Reviews. I was planning on purchasing 2 of the Eco Tune has savers from their website. However, I decided to check with Amazon for a price check. Amazon did not list the “Eco Tune” but had the “ecoobd2” plus many,many others listed. That is when I determined that all of them was just a scam as many of the reviews indicated. So, I decided to do some research at Dani Reviews. Thank you Dani Reviews, you saved me over a hundred bucks.
