It depends on what you call "synthetic". Ever since Mobil lost their spat with Castrol in the late 90s, all synthetics made in North America are allowed to use Group III base oils, which is basically conventional mineral oil that goes through an extra refining process to remove wax. Using a Porsche A40 spec'd made in Europe synthetic will virtually guarantee a high quality Group IV oil.

Don't bet on it, there are very few mass produced Group IV oils available in the market, and exactly none of them say Mobil 1 on the containers.
