Review on Hy-Per Fuel Complete Gas System Cleaner By Rislone by Brandon Garrett

I'm restoring a 1993 Bronco (fuel injected) that has been in semi-storage for several years, but it was run occasionally. I changed the filters and the stale gasoline (was treated with SeaFoam), but it was still idling a bit rough with an occasional miss. Having bought the Bronco new, I also recall having other fuel system issues that were stubborn, even with the Ford Dealer working on it. OK, time for the "Mechanic-in-a-Can" approach. I added this treatment, the whole bottle, to a bit under a half-tank. That was followed by 5 gallons of gasoline to get it all down the chute and help with the in-tank mixing. After driving it for 10 miles it was parked for 5 days. It was then driven another few miles when I stopped at an intersection where I really though the engine had died. Nope, the tach showed 600 RPM solid; it was running, very smoothly. So far it has remained like that (fingers crossed). So my fix was 1 Bottle to 12 gallons of gas and let it work.
