Sorry asking AGAIN. My car has an oil leak, I can see there are daily dark/black spots under hood. Today, there was a HUGE spot and when I checked the oil, it was OVER the fill /full line... o.O Anyone know what it meant? Then tonight, it is UNDER the fill line....saying I need a half quart.... Idk what to do. Some have said don't get it fixed if its a small leak, which it has been, however now there was a giant spot earlier. but for last few hours, practically no leak... any ideas????
