While I was at the backroom at walmart I saw Pennzoil Ultra in flavor 5w20, 5w30, and 10w30. On the 6 quart box it says "Superior Synthetic 35% more sludge cleaning than base oil." Something along those lines.
Sorry I dont have any pics but the 5qt jugs look different from traditional Pennzoil 5qt jugs.
