Toyota Corolla Catalytic Converter
Toyota Corolla Problem

My Corolla had the P0420 code. The fuel line was recently serviced, and then this code came up within days afterwards. This car has been burning oil for years. I have to pour about 10 quarts a year into the car. I went ahead and got the catalytic converter replaced, though I am not sure if this was necessary. The car has 170,000 miles so I assumed that the part probably was worn out.
Engine burns oil which destroyed catalytic converter
