Hi Maurice
I know this has been done to death, however you've mentioned on a recent post a question regarding servicing which went something like "do they use Porsche approved fully synthetic oil" I get my car serviced at RLR in Teesside who prepare Porsche's for the Carrera Cup and such like. They only recommend semi-synthetic, Shell Helix actually on the basis of synthetic can be a bit thin (or something like that) I take their word in the fact that they perform as a performance support team in top Porsche competitions and should know what their on about. Do you recommend on my next service I request fully synthetic?
 
Have to admit that I am not a fan of Mobil 1, currently using approx1ltr/1200 miles in the 955 TT.

If your guy recommends semi-synth, then go with that recommendation as he obviously knows what he is talkig about
 
There is no difference in thickness between a semi synthetic oil and a fully synthetic oil of the same viscosity. The myth about synthetics being thinner is that when switching to a fully synthetic oil your're probably going from a 10W-40 or 15W-50 oil to a 0W-40 or 5W-40 oil. It's the change in viscosity that accounts for the thinness.

BTW Shell Helix Ultra 0W-40 and Shell Helix Ultra 5W-40 are both on the recommended oils list. Don't know if that is what they are recommending or if Shell Helix is something different. If you find out the exact oil and viscosity you'll probably get a lively debate on it's suitability :)

Maybe that particular oil is "recommended" on a profit per litre basis?

I would ask them specifically why they are recommending a semi-synthetic oil. The advantages of fully synthetic oils are well documented, and not the product of one companies marketing department.
Don't necessarily let the fact that they run race cars pursuade you, race car engines are routinely stripped down and rebuilt, so the oil never gets a chance to break down - resistance to deterioration is one of the prime advantages of a fully synthetic oil.
If the oil is on the Porsche approved list, then obviously it should not be doing the engine any harm - but check carefully, as "Helix" is a brand name used for a variety of oils. If the specific Helix version they use is not the one on the Porsche approved list I would definately quiz them as to their choice, as they may not be purely influenced by whats best for your engine [;)]

My 2p, in the end if you are happy with the people then it's your choice
