Years of working closely with Driven has made me biased. For a conventional oil, I recommend their HR1. For semi-syn, GP-1. For full synthetic, DT50.
However, there are lots of other oils that are popular with other builders. Jerry Woods swears by Swepco and they have consistently made a great oil that hasn't changed ever. Likewise, Motul 300V has always been a phenomenal oil.
From the UK, Millers is an excellent choice as well. Karl Poeltl imports the stuff from the UK. It's expensive, but I have run it and believe in it as well.
Lots of good choices, but none that you can get at Walmart or your local FLAPS.

My shop is using Schaffer’s 15-40 in all the air cooled cars. I don’t know anything about is but it is a really good shop!

Charles: I just bought a 1996 993 with 9800miles. Every year the owner had a synthetic oil change (mostly 0-40Mobil) at his Porsche dealer. Except the last two years, that dealer switched to Porsche Classic. Question: would you recommend going back to the full syn Mobil or continue with the Porsche Classic? Thanks.

Can anyone comment on the Schaffer’s “racing” oil in 15-40 that my shop is using? I have not heard of them.

Swepco 306, Driven GP-1/DT50, or Millers Nano are all good oils. There are other choices, but these are the ones that I use and can recommend. I'm partial to Driven since I was involved in the development process with Driven and have run these oils in Porsche engines.

I can't say it is great or better than any of the other recommendations here, but it works well for me as far as I can tell.

I also in the process of updating out Oil FAQ, which has our recommendations on what is the best oil for a Porsche as well as other useful information for any Porsche owner.
