Oops...Too much oil
Hey guys. So I just changed the oil in the 6.2 last weekend and went to double check it today and I easily have 1/2 quart too much in there. My 6.2 is a 2016 and the oil level is just below where it says FoMoCo on the dipstick beyond the hash marks and the upper hole.
Should I pull the filter and empty it and reinstall to lower the level or do you think I’m ok until the next oil change?

I’m not positive what went in. I finished up 2 5qt jugs that were partially full and then topped it off by opening a new 5qt jug I just bought so very well could be my own oversight.

1/2qt is nothing! Just run it. The oil pump is going to circulate the same amount of oil whether there is 4qts or 8qts in the pan.
There is a point where overfilling is bad, but in these trucks, it would be 2+ quarts over or more. The issue with extreme overfilling, is that the crankshaft splashes around the oil in the pan and creates air bubbles (foams the oil), which then can cause air pockets in the pump and oil passages in the engine that can starve the bearings of oil.
Think about it...1/2qt of oil spread over the entire area of the oil pan is nothing! Also, when you start the engine and the oil pump starts flowing, the oil level in the pan drops far away from the crankshaft as the oil is pumped through the engine and filter.
My Cummins calls for 12qts for an oil change. I always put 12 in the pan and 1 in the oil filter for a total of 13qts.
My motorcycle (998cc) calls for 3.25qts, and I run 3.75qts in it.
Never a problem

If they wanted you to run more than 7 quarts of oil they would have said 7.25 or 7.5. There’s a reason for what they said. Personally in my truck I would drain it down to the correct amount.

I am rather surprised of how often this topic comes up (across a half-dozen automotive forums I'm on, not just this one)
We also find out who doesn't understand how an engine works in these threads...

After looking...I am correct: There is a footnote (3) next to the capacities in the owners manual. That footnote states "Add 1 quart for filter replacement" This brings the total to 6 quarts with a filter change.
