Oil Loss

A friend has a 1999 Dodge Intrepid and it runs low on oil, but there is no sign of a leak. Any ideas? Thanks loads. LOVE CAR TALK.

It’s probably burning it. If it is a mild problem, the catalytic converter could mask it. First thing to do is to check the PCV valve. If it is plugged up, it could speed up any oil burning.

Thanks. I put Bardhal into it and seemed to help. Will relay the info. Many Thanks.
