I have inherited a 2009 GMC Envoy with 53,000 miles on it. What products do you recommend I should use to clean the inside of the engine valves and fuel system and how often ? Thank You.

We recommend B-60 High-Mileage FUEL SYSTEM REJUVENATOR (part #7516). This is our best, most robust gasoline fuel additive. It will clean combustion chambers and fuel injectors in all gas engines (including GDI) as well as intake valves in non-GDI engines. We recommend using this product every 10,000 to 15,000 miles.
In addition, for preventive maintenance we recommend adding one can of B-12 Chemtool Fuel Injector Cleaner (part #0116) every third fillup.
