Why cheap syn? IIRC, the rings like to coke up due to undersized drain holes in the pistons, leading to the oil getting really hot. Synthetic ought to handle the heat better, and be a minor price bump.
Great advice.
This is an old car, yes it will burn oil but it will still runs.
You have to shoot it or the body will let go first before the engine as long as you maintain it.
