GREAT PRODUCT
Great product! This stuff is helping my truck run great. I live in an area that there is not 1 good fuel station with certified gasoline with cleaning additives. At least not that I have discovered. By adding this product my truck is getting the lubrication it needs and the cleaning agents it requires to keep the injectors plus the O2 sensors healthy. It works and MADE IN THE USA!

Be careful on dosage
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.

Injector cleaner
This product works miracles on my ole Cadillac sts 07. She runs smoother and seems to have more pep. Highly recommend this product.

Helps engine health.
This product works keeping injectors and othe vital components clean from carbon. This is critical if you’re not using top tier gasoline that has the appropriate detergents. I use when I can’t find top tier gasoline.

Smoothed out a rough idle but no better mpgs
So it’s a little more viscous than Lucas fuel treatment and was priced well but after 2 32oz bottles and thousands of miles my mpgs did not improve. The engine appeared to run a bit smoother and acceleration was a bit better but that extra oomph disappeared after the first tank.
