thank you for your attention to the rating requirement.
this may or may not be serious. the common causes of oil burned would be a failed crankcase ventilation system, leaky valve seals or internal engine wear. If the issue is seals or wear, isn't really worth fixing on a vehicle this old so you should just live with it. It is not the catalytic converter so whoever told you that is not very familiar with this car. Oil change capacity is 4.25L
