Going to change the oil in a recently purchased 87 GN with 95K miles that as far as I know has always had regular motor oil in it. What is the advantage to switching to Mobil 1?

Synthetics have very high anti-wear characteristics, and very high temperature tollerance. The latter is a big factor in a turbocharged engine since the turbo bearing rides in (and heats) the engine oil.

You may want to address any small oil leaks before you introduce the Mobil 1. Synthetics have a way of making leaks appear where none were evident because of their improved lubrication characteristics.
