Fuel Saver Pro, Saving Approximately 15% Fuel, Fit for Models After (2PCS)

The media could not be loaded. These are not fuel savers. They blink LED lights inside their green lid. That's it.Resetting your fuel mileage to test and then driving carefully will raise your fuel mileage.That will happen with or without this plugged in. Buy one and open it. Check it yourself.The OBD2 port has 16 pins. Only pins 5,6, and 16 are soldered to the circuit board.Those are the pins for 12V power and ground. This is just pulling power from the car.Selling a blinking light as a fuel saver is a scam.

I'm like most people, i.e. I'm a skeptic about things like this, and claims by people that it does work. Well, they were cheap enough at $3.50 each, and it looks like Elon Musk endorses them, so I bought two for my vehicles. I have a 2011 Nissan Frontier with a camper shell, and I was getting only 15 - 16 mpg when I drive it. I followed the instructions and installed one. I waited a couple of months to start checking my milage, because it was a real gas hog. Two weeks ago, I checked my gas milage and found that I was now getting 21.5 mpg with this installed, and I was happy, but this past Wednesday I had done quite a bit of interstate driving, and this time when I filled up and checked my milage It was astonishing, because I'm now getting 28.4 mpg. This device has almost doubled my mpg! Look, for $3 to $4 dollars you're not going to lose anything by buying one these, and I don't know that everyone will experience as much of a change in their mpg as me, but it's worth trying! I'm a believer now!

I bought 4 and the 4 vehicles that they were put in got worse Miles per gallon. Unplugged all 4 and mileage went back to normal. I wouldn't recommend this product as it does not do what it states. Have 3 back in the package but can't find the 4th. Would love to get my money back. Also was shipped from China.

To my surprise my 2016 jeep wrangler is saving gas every time I’m in it!! Great product that keeps on giving $$🙏🏻

Brought fuel up and more power. Bought 2 more for a family member

I'm NOT seeing any fule savings @ all I've it for over a month now & I'm just not seeing ANY improvement; In fact unless my fuel gage needs sirius calabrating I'm Getting Less than 5 miles per gallon I drive a V6

It helped my fuel mileage and it will work for you too.

Gas SaverBest I can tell it shows it’s getting better mpg but a check with the miles per fill up divided by gallons isn’t as good.I may have it wrong because there is a super chip bypass installed and it blinks all the time when I turn the jeep off.
