Krisness adds:

As an owner of an old 1978 911sc, my mechanic told me to NEVER put fully synthetic motor oil in an old Porsche. It's too thin and "finds" leaks. He said once you put fully synthetic in and try to switch back the leaks won't go away. He said synthetic blend every time. Looks like someone from the original entry wants to sell something.

Porsche paul adds:

I am a PCA member and own several Porsche's and the first answer was Absolutely the best answer. Mobil 1 Synthetic oil is the recommended oil for this car due to Oil Viscosity. Although Krisness thinks it is thinner, is is actually not really. The reason her car may have ran on old crappy oil and covered and clogged over any leaks she has one the car. We of the mechanical world call that Engine Sludge. She could be right in staying with that oil to save herself money as those before her mistreated her car too. But her car will suffer in the long run as it is robbing her of power and also left untreated those leaks she is hiding will become major later. Sort of like hardening of the Arteries and buildup of cholesteral. I for one want the best for my baby and am preventitive maint. oriented. So i want to fix the slight drip before it becomes a gush. And regular oil viscosity will break down at 300 degrees; verses synthetic which doesn't begin to even break down till well above 400 degrees. That is Super important if you want to take your Porsche out for an extrended drive or even if it sits in your drive/garage for a longer period of time. Viscosity is the key to oil.. keeping it the best you can.. Mileage is important for helping determine oil change. But breakdown in viscosity is real reason.. reg oil barely lasts 3000 miles.. but it can break down even faster if driven hard or hot. Synthetic won't. Think of a Battery.. Regular or Alkaline... which one will break down and not hold a charge first? Which one can you leave in a drawer for months/ years and it still works?

Oil is a cheap thing to buy compared to a New Motor..
