Today I’m purchasing a 2014 2500HD 6.0l with 225k miles. It was used as a delivery truck for trailers. Single cab, 4x4. I’m buying it to tow boats and use for general use when I need a backbed. It will see about 1k miles a year just towing to the boat ramp, taking boats to get filled up, etc.
Given that it’s high mileage what oil should I be running? Whats the difference in High Mileage vs full synthetic? In my B58 grenadier I’ve been running Quaker State Euro 5w40 and I’d think if that oil is good enough for the turbo charged B58 then it should work well in a NA 6.0L but with this high of mileage I’m unsure what I really need.
