Try Shell Helix, I use it in a 944 turbo, lots and lots of track miles, changed every 3000 miles.
Leading evidence: 'Replace every 3000 miles' (no explicit attributable resolution; this is a reported action or suggestion).

Mobil 1 15-50 here, car seems to like it and it's only about £2.50 ltr here, so it gets changed often.

After watching the new 996 and boxster engines being bench tested with Mobil One on a factory tour last year (and finding it difficult to avoid the huge Mobil One signs everywhere) I expected my 87 Carrera to have been refilled with the stuff when I picked it up after servicing by their Customer Centre.

Suggestion
The Porsche Factory Customer Centre seem to place some importance on the "original fill" oil make.

My engine still had the "Shell Original Factory Fill" sticker on it and they had religiously replenished it with Shell Helix Ultra.....

However lots of the Porker specialists (independents)use the Castrol range with Magna-Tec very well rated(it is a semi synth)and the Iguana gives it his vote.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

OPC's only use Mobil 1 (Although I havn't had dealings with an OPC for a year or so).
Any decent fully synthetic oil should be fine, although I've always used Mobil 1.
Yes, Mobil 1 seems to be common consensus on this. Even the independent garages chuck it in (well mine does).
I would be tempted to try Mobil 1 Motorsport 15W50 rather than 0W40, but haven't yet. It may be worth asking the question because I always thought normal Mobil 1 was slightly too thin.
The Motorsport vs regular Mobil 1 debate has been raging on the TVR forums for years... as has the fact that in the UK, Mobil 1 is 3 times as expensive as it is in France or the US for no obvious reason.
I'm used to buying all DVDs from either the Channel Islands or Australia as both are much cheaper than the UK, so maybe I should investigate importing a quantity of Mobil 1, say 100 litres or so
I think you'd find it hard to convince customs that 100l of Mobil 1 was for personal use only. Especially as you don't own a TVR anymore
.
Just kidding!!!!!!
I wonder if PCGB or the TVRCC could get together and do a "Mobil 1" convoy to France. Stick a load of Mobil stickers all over the cars, drive to the nearest stockist and buy their stock.
"Yes, sir. This bootful of fully synthetic oil will be going in my car, sir. Oh yessir, yes it will."
"Drinks it like it was going out of style, oh yes!"
Ref oil for ya porker. Older aircooled pork can find Mobil 1 a bit too thin and guzzle it a bit and yes many people do use Mobil 1 Motorsport in for that very reason. If you like mobil and want a semi synthetic Mobil Super S its very good and suitable for all non turbo pork. However lots of the Porker specialists (independents)use the Castrol range with Magna-Tec very well rated(it is a semi synth)and the Iguana gives it his vote.
Castrol slx is a rival to Mobil 1 and is also a 0w oil but again as with Mobil 1 oil consumption can be an issue. If ya want a slightly thicker fully synth oil use Castrol RS (10w) just like the motorsport boys do.
Its not just old porkers that dislike Mobil 1 the high tuned AMG Mercs tend to guzzle it a bit too, switch 'em to Castrol Magna-Tec and the oil consumption stops!
Ps- I don't work for Castrol!
You will always get wear on turbos with too thin an oil - not just a VW problem. This is because the turbo bearing 'sits' on a thin film of oil. Too thin and it doesn't float properly.
That is why I always used to put 15W50 in my Lotus Carlton - 0W40 would have shagged the Garretts.
Try Shell Helix, I use it in a 944 turbo, lots and lots of track miles, changed every 3000 miles. Cheaper than Mobile 1, dosn't burn away away as fast as thin Mobile 1.
Buy all oil in French Hypermarkets, half the UK price, same grade, and generally 5 litre pack instead of UK 4 litre.
Mobile 1 goes into my wifes Merc diesel, yep thats right. Merc dealers put Mobile 1 into diesel cars.
It's very quiet in here today, so here's an entirely gratuitous picture of the thing that will be needing the oil
I had to take out the CD player to get the luggage in though.
Thanks for the compliments!
I am expecting to fit a sports exhaust, so I am looking for suggestions, prices, where to have it fitted etc. It may have to wait a few months before it happens because of holidays and other upcoming expenses, but it is definitely on the cards.

Not a bit of it. My engine still had the "Shell Original Factory Fill" sticker on it and they had religiously replenished it with Shell Helix Ultra.....
Have run it for a year since topping up with Ultra and it seems pretty happy.
I was just wondering what brands/grades of oil you other air-cooled people are using. Fully synthetic presumably? And what do OPCs and specialists generally use when changing the oil?
