Hi there,

Sadly, if the car is burning that much oil, it's usually an indication that there is an issue with the oil rings or the cylinder walls. This is going to mean a rebuild or replacement engine. The heat issue may be a sign of a bad head gasket as well, although if you have auto climate control it could be a malfunction of one of the sensors. The only way to be 100% sure of the cause of the oil consumption issue is to have a leak down test performed on the engine. Basically compressed air is blown into each cylinder one at a time, then you listen for the leak of air. If you can hear it in the engine when you remove the oil fill cap, then the rings on that cylinder are bad.
