You're going off a recommendation that is nearly 40 years old. The Shell gas (and the agreement they had with Porsche back then) has changed in the last few decades.
My BMW (under the hood) says to use Castrol motor oil. But since that car was manufactured BMW has switched their contracted oil supplier to Shell/Pennzoil, which is what you'll find labeled under the hood of new BMWs. I'm confused - what to do...
Actually, I don't follow their suggestion at all and have been using my own choice of oil for the last 150,000 miles (almost 200K on it now).
