Same recommendation as the newer cars, synthetic oil is the best you can get and it won't hurt an older engine at all, it's much better than conventional oil.

some cars cannot adapt to the synthetic oils so sometimes the old and the real oils are better. Also some synthetic oils are nixed with "chemicals" not good for old cars...

For older engines its best to use conventional oil.
