I need your help understanding what I see in the bottom of the "pure" Ultra Platinum Pennzoil oil.
After changing the oil in our '15 BMW X5, I noticed some "dark" stuff in the bottom of the 5 qt jug. What is thins stuff? I thought that this was suppose to be the Purest motor oil since it's made from natural gas. AS I understand it, BMW switched form Castrol to Shell (who owns Pennzoil) because it was so PURE.
Can someone tell me what this stuff is
