JE Bar........this is exactly why I add 11 qts at each change. It's 1 qt from the last "bar" to the very top of the in range xxxxxxx mark. I've checked it hot, cold, level, same day, next day whatever.
Only thing I can point to is I let it drain 30 minutes everytime I change it and maybe I am getting just a little bit more of the old stuff out than everyone else is. I also change it on a steep incline with bolt hole pointing down. Anyway, I change it every 5K and been this way last 20K (4 changes) always 11 qts to the very top of the in range mark. I like it full as it runs cooler (in my mind, more oil is more cooling capacity).
So put in 11 qts and smile, by the time you are ready to change it again you will be where everyone else is when they started out after a change, down 1 QT. LOL
