It was only down 1/2 qt. I was getting ready to take off on a 1000 mile trip pulling a trailer and I just wanted to top off the oil in order for the engine to have plenty. What weight do most of you use? I was thinking of going to 15-40 at the first change.
I have a new 2011 6.7 power stroke with less then 3000 miles. I see it can use a little oil added. Does anyone know what weight oil is put in at the factory?
