The best fuel injector cleaners use PEA detergent additives %26 Techron leads all reviews. This 6-pack of Techron is the best deal on the internet. Just add an entire bottle every oil change or 3000 miles.

It works!  unlike other products which claim to work but don't, This product worked on my 2008 Dodge Avenger within two days.  It use to take several turns of the motor to start the engine, but now after two days the engine turns over and starts immediately

I seen this on a YouTube channel and thought I'd try to have a engine light on and I knew it was from my air sensors after using it for three times the lights gone out and hasn't been back on since this is something that I use on a regular basis for maintenance

This is a great product. I'd highly recommend it.

Based on multiple reports, this product essentially is THE BEST additive for clean fuel injection systems. Naturally the gas we fill our tanks with is primary, but this solution finishes the job.

Cleanest of Cleaners

[This review was collected as part of a promotion.] This is known to be one of the best.ive used it several times in several vehicles.pays for itself in gas savings.

It works

[This review was collected as part of a promotion.] My car has high mileage so I didn't realize they had one for that but this definitely made my ride feel a bit smoother. Plan on ordering another one for the high mileage.

It's alright with me!

One of the best fuel system cleaners you can buy. This box of 6 bottles was the best price anywhere. I highly recommend this product for maintaining your fuel system in your car or truck.

The best at the best price!

[This review was collected as part of a promotion.] Car is running better, acceleration is a bit smoother.  Will use this again.  Thought I was getting gas at a Top Tier level station, turns out I wasn't.

If you think all gas is the same, you'll want this

[This review was collected as part of a promotion.] I tried this product about a month ago. It has improved the performance of our vehicle. The engine runs smoother.

Good fuel injection cleaner

Rotten bottle design prevents you from emptying the entire container into the gas tank.  I googled this and discovered that I was not the only person who had this problem. One of the suggestions was to knock a hole in the bottom of the bottle so air can enter it and allow the entire contents to enter the gas tank.  next time I'll buy a different product.

unable to empty the entire bottle into my gas tank
