Has anyone had any experience with these engines? Looking for opinions? I am looking at a C6500 with a 7.8 in it? Seems to be a fairly strong engine with a life expectancy of 410,000 miles per the owners manual.
I was looking at them for while, was looking for one 1-2 years old. Asked around, fuel mileage was the biggest complaint compared to the rest of the med duties.
Where these trucks automatics or manuals. What type of mileage where they seeing and what type of trucks where they. Thanks
