Chevy Silverado Forum (GMC Sierra)
Hello!!
I have an '08 Chevy Silverado 1500 4WD with a V8 6.0L engine. It is not a FlexFuel.
Originally I had taken it to Autozone to use their diagnostic device and it threw up a code that said I had "dirty fuel injectors." So I have used the Lucas brand Fuel injector cleaner in my fuel tank...
