Techron will clean valves as well. Now that I use top-tier gas I don’t use the techron any moreAs a fuel additive I’ve always used the Lucas fuel system cleaner. I’m more interested in cleaning the carbon buildup on the valves due to our GDI system. That’s a more involved process and was wondering what everyone did for that
