Unfortunately I am having to add at least one quart every couple of hundred miles. The gas mileage has not decreased at all and I get at least 20 mpg.

The CEL has really been on prior to this issue. It was showing a 420 code before even after I had one of the Cats replaced almost 2 years ago. I am thinking all of the smoke in the morning is not good at all for the Catalytic converter.

I will definitely check into the EGR valve.
