Car is having grey/blue exhaust smoke coming from the exhaust. I read online it is burning oil. What are the common problems why it would burn oil? Once the car is on it purrs like a kitten.

Hey Alex. A car will burn oil like that when there is a problem with the valve seals or sometimes the piston rings. What is happening is that the seals/rings have worn out or become slightly burnt and are now allowing a little oil to get by. That oil seeps into the cylinders while the car is running and burns, creating that bluish smoke that you are seeing.

It explains everything, including other possible causes. As always, let us know if there is anything else that we can do for you.
