I recently purchased a 2008 Coblat and when i changed the oil i noticed mayonnaise under my oil cap. the car was sitting in the lot for three months before i bought it and i have been driving it long distance for about two months now. the car only has 20,000 kms on it so what could be causing the mayonnaise? the oil was fairly black when i changed it and i wasn't even at
3000kms since purchase, could it be that the dealership didn't change my oil for a long time? Melissaurl:
