I have a 2017 Chevy Silverado with over 103,000 miles on it. I currently have a P219A code and am wondering if adding fuel system cleaner/fuel injector cleaner in it will help clean things out and improve my gas mileage which has taken a bit of dip. Are these additives worth using and if so, what type and brand is recommended?

Scotty primarily recommends ATS 505 fuel system cleaner, and also PEA-based cleaners such as Techron.
Bear in mind that many things affect gas mileage and fuel system cleaner will not necessarily help.
