If you’re skeptical of a product I understand I was too. I drive a 2014 Hyundai Elantra and I decided to give this stuff a try for my recent car tune up. I’ve seen people use it on YouTube (specifically mechanics I follow) and they love it so I tried it. And I have to say I’m surprised, obviously it’s gonna be a slight difference in driving but a slight difference goes a long way when it comes to car health. Do your own research before you use but for my car I liked it and I’ll probably be getting the oil treatment they have too!

Saw this promoted by Scotty, and legit it works, fast! Never cleaned any of the fuel injectors before, and my truck has 329K miles. It was driving oddly in first to second gear. Added this in tonight, drove 11 miles, problem gone!! I’m a fan of this new company. Made is the USA! Expensive, but well worth it!!

My cars idle smoothed out big time. The acceleration, gas mileage and power also inproved. The price is a bit much ,but it is worth money. This is the only fuel system cleaner that I used that actually works.

Easy to use. My engine is noticeably quieter. Running temperature is a bit lower (per the crude dash temperature gauge), and mileage is up about 5%. Scotty was right!

Wow. Notably better gas mileage after using this.

I have an older small SUV that had become sluggish when accelerating and I decided to try this based on the recommendation of an old time mechanic, on YouTube, whose opinions I trust. I waited until my gas tank was near empty, added this product and filled the tank with premium gas. I used up the tank of gas driving, mostly, at highway speeds and have since noticed better response when accelerating. My guess is that it cleaned the fuel injectors to some degree. This stuff is expensive, so I probably wouldn’t have bought it if there wasn’t already an issue. All in all, it worked to my satisfaction and I’m considering using it once a year to maintain the car’s performance. I would have given five stars if it wasn’t so expensive.

Best on the market

Product burned with fuel no adverse fueling effects. No way of telling if it works. Car really didn’t experience any changes. Will try again in future. 2001 BMW 530i 184k miles. Engine runs very good before treatment. Thank you

"Great product, did what it was meant to do."

I put a new filter and oil with this oil system cleaner in a car with 122667 miles. I idled the car at 1500 rpm for 45 minutes. Then drained the oil. It was far blacker than I expected. This cleaner works very well.
