It did not improve mileage by even a tenth.

Two pieces of this item were detected faulty on arrival. But the rest items are in good shape. The manufacturer of this product advertised 30% fuel save but the performance is not up to that rate. Can you reach the manufacturer and see if they can upgrade to 30% or more that will be better. Also can you do anything to the faulty once. If nothing can be done, then forget. Thanks Francis

my gas milage has increased 6 mpg while driving 60 mph.pretty good. I drive a 2012 GmcAcadia.Bought the car new i had a shark but some how lost it when i took the car to have itwashed.

It was not compatible to my car it did not work

Works really good and save money on gas

It doesn't work. Miracles are not exist.

I put this EZ Fuel Saver in my car, a rusty '81 Plymouth Horizon that had a leaking carburetor and a weak alternator and that often stalled at stop lights. Like many other reviewers here, I didn't notice anything different in the car the first day I ran it. However, I let the old car sit sit in my garage overnight, then when I came out the next morning and found that my car had somehow transformed into '70 Cuda with a 426-cu Hemi. The car looked perfect, with a flawless metallic coat paint job and spotless chrome. Shocked, but needing to get to my pizza delivery job, I went ahead and got in and started it up. My old key still matched the ignition perfectly. With a quick rumble, the engine started up and idled with the most perfect sounding idle I have ever heard. I stepped on the gas a little bit and the engine revved slightly with a sweet sounding purr. I was running really late for work, so I put the car into gear and carefully backed it out the driveway. On the way to the pizza shop I noticed every light was green, nobody cut me off, and when I arrived I was actually 10 minutes early! Also everything about the car seemed to work like it was brand new.I had to deliver tons of orders that day. Each one I made it early and also kept getting by far the best tips I have ever had. I think by the end of the day I had $700 in tips. Crazy, but I wonder if it had something to do with the car. Also a lot of the deliveries the people looked like they were having some pretty sweet parties and they invited me in, but I told them I needed to finish delivering my pizzas and get back to the shop. They told me to just come back whenever I had some time.But getting back to the car now -- I never saw the gas gauge drop all day. In fact, it started going up. That morning I had about 1/4 tank, by the end of the day I had a little more than half a tank full. Since then I've had to start draining gas out of the tank every few days and then waiting for it to fill back up. I'm not sure what I'm going to do with all this extra gas I have now but I'll figure something out. Otherwise though the car has been perfect since I put this in. Thanks EZ Fuel Saver!!
