So I was checking my Mazda 3 for oil. I checked it 3 times within a week and it was a quart low so I decided to add a quart. Decided to check it again today, about a week after doing this and its now showing a significant amount over, it looks as if it is a full quart over. Assuming this is a quart over (has 6 quarts in a 5 quart pan) should I drain the quart or just run it?
