Review: Will continue to brag on this great product! - Traveling to FL and added to my RV. I find it hard to explain the great job this product did. Obviously cleaned out crude I didn’t know existed in my vehicle. A marked increase in performance and mileage!
Review: Keep you car running smooth. - Use this from time to time to keep your baby running smooth. I "juice" my gas tanks up with this by using extra on a low tank of gas then let the car sit either over night or a couple of days. Then take it out and run it hard for 50-60 miles or so then fill the tank. You can feel the difference in the smoothness of the engine as well as easier starts.

### ⭐⭐⭐⭐⭐ Keep you car running smooth.
*by M***H on October 27, 2025*

Use this from time to time to keep your baby running smooth. I "juice" my gas tanks up with this by using extra on a low tank of gas then let the car sit either over night or a couple of days.

### ⭐⭐⭐⭐ Be careful on dosage
*by C***R on January 2, 2026*

Good cleaner but watch the dosage. I put around 4 oz in a 1/2 tank and started getting rough idle and stutter/misfire due to dilution and bad combustion. Once I filled up the tank issues were gone. Just be aware and follow recommended dose.
