Hello, I opened the oil cap today after I drove thecar and I saw a drop of smoke coming out. I checked the oil level and it was half and when you loko inside and wipe your finger on the wall inside the engine black dust it looks like comes out. What is this. Also wil castrol high mileage clean this up. Does the oil filter help with removing this. Thank you
