I have a 2000 jetta that is consuming oil. I am worried that this is not normal. I'm putting oil in about every 1000-1500 miles. The dealer gave me part of a technical service bulletin specifically regarding oil consumption...I'm worried he left out the pages saying my consumption is abnormal. They say this is normal and that the car has no leak. I see other people are having this problem too. This is bizarre. Should I sell? Should I buy an extended warranty? Or is this car defective and a lemon? My heat sensor has already been replaced and so has my glove compartment door. Is there a mechanic out there who knows whether or not this could be "normal" as vw is contending?
