I think the use to which you'll put the car should come into play in the choice. Many of us drive our collector cars perhaps 1000 miles a year, and long, sustained drives tend to be the exception. If that'll be the case with you, such use tends to increase the propensity for collecting moisture in the crankcase because the road-draft tube system isn't particularly effective at low speeds and lots of idle time. If that's the case, you're better off to change the oil annually or at least at 1000 miles intervals and in so doing you gain none of the extended oil change interval benefits of a synthetic.

But whatever you use, use top grade product and change it regularly and no less often than once a season. Many of use who lay up our cars over the winter change oil just before we lay them up for season so they sit without the accumulation of moisture, combustion by-product acids, etc.

And if the car ownership is new to you and you don't have prior history of maintenance, drop the pan and clean it and the pump intake screen.
