Exactly. Any premium engine oil, conventional or synthetic, in a grade suitable for your geographic area/ambient temperatures will work fine in your "antique" engine. It's vastly better in that engine than what the engine got for the first 40-50 years of it's life. For most people that grade would be SAE 10W30 and suitable for year round use.
