Ok...I got this car since February I did tune up oil change all that stuff..This Saturday was the first time I took it for a long drive...total 250kms. I decided to check the oil today and it was all gone!...What happened??. There is no visable oil leak to speak of that I can see or it would be all over my driveway. Anyone know why it would be burning that much oil?...How serious is this?...
