If your engine leaks oil, no you should not use synthetic oil because it will clean sludge and can make the leak worse. If your engine does not leak oil, I would highly recomend using synthetic oil(Pennzoil Ultra 10W30 from Walmart is a good and pretty cheap choice). As long as your engine does not leak oil using synthetic oil is a great choice regardless of how old it is.
