What is the best kind of fuel cleaner to run through my 3.0 Liter Ranger. I have heard some bad things about using fuel cleaners. My truck runs fine but I am just curious what you guys think.
I use Outlaw, made by SNAP. They have fuel injector cleaner, gas treatment, and octane booster. It's the only brand, that I've tried, that made a noticeable difference in my truck.
