Review on Hy-Per Fuel Complete Gas System Cleaner By Rislone by Mark Saric

I used the oil treatment and had great results quieting my engine noise on my 14 kia forte with 120k. Decided to try the fuel treatment to help with rough idle. This worked just as good as the oil treatment! My car is now as quiet as when it was new, barely hear it running standing right by it! This treats 22 gallons but my car only has about 10 gallon tank. Tried to pour in half bottle but it didn't come out even so I dumped the whole bottle in and filled up the tank. Within first 1/4 tank it was smooth as a kitten. Ran to 1/2 tank then filled up again to get it to intended strength and get more our of the bottle. This stuff works better than any of the other stuff I have tried. Gumout, Lucas, techron only gave 1/2 the results I got with this. This will be my go to and recommendation from now on!
