i have a 01 GMC dully the injectors went out at around 85k GM replaced them with Bosh injectors and no problems since i have 149 k on it now and it runs real strong,i get 17 to 18 mpg on the road 11 to 12 towing our rl3 . i keep it around 60 to 65 mph . At every fill up i pour in a qt of Marvel mystery oil, it helps with mpg and does a great job of cleaning injectors
