They dont work. Dont waist your money.

Lie lie lies! I bought three of these devices and gave them to my family members. The results were very consistent! For all three of are vehicles we didnt see any different in the fuel performance of our vehicles.

So, save your money. Go and check the air in your tires because that will save you more money than this product.

Company cannot back its claims

I ordered the Effuel chip back in March, 2021. I received no email confirmation of my purchase, so about a week later I called the customer service number shown on my original sales slip from the online sale (I had the presence of mind to print out that document).

I asked the person who answered the phone to look up my order number and verify that my product had been shipped. She said that it had been shipped. I then asked her to send me that shipping notice to my email while I waited for it to arrive. I waited about 5 minutes while still on the phone with her, and my email still hadn`t arrived.

She made two more "attempts" with no results. I asked to talk to her manager, but she said she was the only one available, so I ended the conversation. Finally, nearly a month later I did receive the chip, followed the installation and "reset" instructions exactly, after plugging the chip into the correct receptacle (in my case, a 2009 Hyundai Santa Fe just under the dash close to the steering wheel area). For some time when I fill up the car with gasoline I always fill it up until the fuel is at the very top of the fuel spout.

Each time the mileage shown between fill ups is 266 miles. Since installing this chip the last three times I have filled my car with gasoline that figure has remained at 266 miles.

Pros:
  • Great advertising campaign
Cons:
  • Claims are completely unfounded

Preferred solution: I would like to see this company cease to exist. They are nothing but scam artists. Most of the reviews online are nothing more than sales pitches using different links with mostly the same paragraphs. They need to be prosecuted for fraud.

User's recommendation: This is a complete and shameless scam. This product delivers ZERO on its claims.
