Added this to my fuel tank of my suv because I noticed the estimated to empty mileage was way lower than when I first got it. First fill was kinda close maybe a few more miles but each fill a few trips after brought my mileage till empty back up!

This product really does a good cleaning job and easy to use, burns out the inside of the engine carbon deposits, I Like The Products!😎👌🇺🇸

I specifically bought this because of the reviews saying the amazing results but not for me. I saw no difference after the first use. I did buy a second one so I’ll give it another try but it doesn’t seem to do anything better than the lower priced companies.

I bought this on July 13th. The estimated delivery was about two weeks I got it within a week of purchase. My Chevy sonic Lt (2015 sedan not the hatchback model) had fuel problems for the past year. It would run okayish on the highway but it would either have a rough idle or start most of the time both. Fuel economy went way down even with oil changes. I was an idiot putting in cheap 87 octane gas from arco. So I switched to 91 octane from shell and other high end gas stations. It improved fuel economy but still had problems as mentioned before. So I read the manual I did most maintenance on the car but forgot the dang fuel system treatment cleaner. I saw that it mentioned this product so I bought it and poured it in a near empty tank then ya fill it up. I ran it on he highway and felt improved fuel economy. Starts and idles improved big time. I will buy another bottle of this and do two bottle intervals before every oil change. One thing I forgot to mention was that whenever I pumped gas when these problems occurred the car would struggle to start and each time that happened I would have to almost floor the gas pedal in park at the gas station. So I’m guessing the fuel injectors and lines were a bit clogged with cheap gas gunk and sediments. so it cleaned my fuel injectors and fuel line systems. If you have any GM brand vehicles buy this and make your car chug it! I got better rpm, starts, mileage and of course no more messed up starts when I’m done pumping gas.

This fixes a fuel system issue any time I encounter a bad batch of fuel. 08 corvette throws a code for bad sending unit for sulfer buildup along the wires. Here's a quick fix
