We're not that old, first thing to do would be confirm where the oil burning is coming from, if the motor has sat a long time, it may simply be dried out valve stem seals leaking oil from the top end of the motor into the combustion chamber. Replacing those may fix your oil burning issues. Otherwise it will be bottom end oil control rings. But it's worth a shot, since I had that issue years ago and replaced the seals and it was fine after.
