regular oils are fine if the 3000k interval is kept.
otherwise go synthetic to extend the oil change interval.
Our car's aren't sports cars that run most of their time in high revs nor does it require synthetic to run. Its basically goes by the rule of your car requiring regular fuel and the owners put in higher octane to think it runs cleaner or better...
Overkill but not a bad idea if you intend to keep your car the next 20 years.
