All the charts list the pan capacity. Not total capacity. 4 quarts for the pan, 1 quart for the filter. #51515 Wix, PH8A Fram or the like. I have been changing oil in Mopars since the late 60's of the last century. They take 5 quarts with a filter. Don't measure how much oil you drain out as a indicator of capacity. I drain it out till it quits dripping, replace the filter and fill with 5 quarts. If your filter is closer to vertical than horizontal, put a little oil in it before starting and put the rest of that quart in the engine..Like SGbarracuda said, 5 quarts with a filter, run it, let it set overnight and check the level the next day. Mark the dipstick if you have to.
