300v most likely is better, but better at what? Actually I believe I currently have 300v in one or two of my motos. I haven't researched all the different Motul products and their applications. The 300v is an ester oil and I have not yet personally had it recommended for use. I've seen the 8100 recommended by several sources including LN eng. I also know the 8100 is Porsche approved, not sure about the 300v.
Bottom line is I'm a little bit leery of the ester base. Is it a good match for vario-cam?
I don't really know. Maybe by the end of this thread I'll be running 300v.

That said the only 0-40 I've found is Mobil1. Spoke to the folks at GoldCrest who run several cup cars and was told thats the only weight to run. GA gets pretty hot too.

Please contact T2, he better stop using Mobil 1 , or the turbo won't make it to 600K miles.

At the track this weekend I hung out with some guys running a '11 Cup car and they were using 5w-40 Motul 8100. I posed the same question: "I thought 300v was better than 8100". Explination from them was that 8100 was what porsche suggests hence what they run. ZDDP content may be slightly higher than the 300v was a possible explination.
I think what we have to worry about in street cars is that while ZDDP is good, too much can cause issue with our catalytic converters.

You want an oil with lots of this stuff: http://en.wikipedia.org/wiki/Zinc_dithiophosphate
Replacing a catalytic converter is a lot easier than rebuilding an engine.

Having said that, I'll be running 300V next change.
Lots of discussion on the 996 turbo forum as well.

There's also great debate on if some of the factory fills actually have what they're rated to have for zink these days. Mobil 0w40 and is listed on their spec sheet has having >1000ppm where some of the other Mobil oils are down around 800 these days, but some have suggested in testing that it doesn't test as high as the spec sheet suggests.
There's a good thread on all of this in the racing forum thats pretty recent.

Fool that I am, I take Porsche's recommendation as the best choice. I did find that Mobil 1 European Car Formula 0W-40 has over 700 ppm ZDDP unlike any other Mobil 1 products and that is a great benefit for reducing wear. Also, the low temp rating ( 0W ) is helpful in making the vario-cam work at startup.

I run Mobil1 5W-50 and change my oil 2-3x a year. The 5W-50 is in my opinion the best weight for my needs as it gives me a little better startup protection with the 5W (over something like 15W) but gives me much better protection at the higher temps than the 0W-40. I used to be a 0W-40 guy until I found a local distributor that stocks the 5W-50. Now both my P-Cars run the 5W-50.
I plan to do an oil analysis after this next change so I can start tracking the utility of the 5W-50.

My 6GT3 is not OHV engine. So, i guess the inclusion rate of ZDDP is not important so much. (Sorry, I don't know the truth.
) If 6GT3 want to drink ZDDP, it may be useful to give the STP treatment which contain ZDDP.
