Hi guys,my 2001 Honda civic has 158,000 miles and runs great. After my last oil change (the dealer) i started seeing oil drips about 800 miles after the change. I check the oil,it is 1/2 quart over full. I am going to drain it and wanted to ask if i should try High Mileage oil this time? All this car has seen its entire life is 5w20 green bottle quaker state. Just want some of your thoughts,i thank you for your time!
