the 15w-50 has the high-zddp additives.
the only regret i have about the above video is that they're using too far an extreme of cold. they would be better off doing that at 18 degrees Farenheit. so i must go back and find a more-realistic, typical-nighttime-temperature video.

According to the specs, Mobil 1 0W-40 has 1000 and 1100 PPM phosphorus and zinc, 15W-50 has 1200 and 1300 PPM, and 0W-50 has 1750 and 1850.
So yes, the 15W-50 has a little more ZDDP, but not a lot, and I suspect the higher wear at startup would more than offset that. Of course, I still draw the conclusion that the 0W-50 is the perfect oil

it appears we've just missed a blowout sale on Mobil 1 courtesy of advanced autoparts.
up to 1 case/customer of the superlube for $47.88.

I finally got around to calling Mobil.
Tech support says that Mobil 1 0W-50 Racing has a detergent package comparable to the other oils like 15W-50, and there's nothing about it to prevent it being used on the street just like any other oil, so long as you don't have a catalytic converter to blow up.
Between the lower cold-start viscosity and the higher zinc and phosphorus content, I'm definitely switching to this stuff at my next oil change. I'll tell you guys how it goes.

the racing oil is 100 bucks for 6 quarts. but obviously the best oil money can buy.

Yay?
I mean...in theory, it combines every characteristic of an "ideal" oil...thin enough to flow as much as possible at low temperatures, thick enough to still lubricate at high temperatures, ****loads of zinc and phosphorus, in an all-PAO base...so does that "win" the "oil war"?
Well sure, in some alternate universe where everybody drives a catless car and is willing to drop $100 on an oil change. In this universe, that comprises, what, 5% of us here?
For the REST of you guys...don't mind me, keep on fighting

I went to this site I read up about oil in general:
www.bobistheoilguy.com
If what is on there is true then what odurandina is actually correct which also agrees with Porsche's recommended oil list.
If this is not true then does anyone have evidence to the contrary that the explanation of oil ratings and dynamics on that site is false?

that's exactly the problem. we have a lot of very smart people on Rennlist. but talk to them about motor oil, and the don't even know what the numbers on the side of a plastic bottle mean... and if that wasn't enough, why would anyone use conventional oil at all when there is something 10 times better to put in the crankcase ?

Just another oil update...
Back when the 968 spent all of its time on the racetrack, it ran on Mobil 1 15W-50 because it mostly spent all of its time at proper operating temperature, with very few startups per year, so the 50 weight was really the only relevant factor.
Since I started daily driving it about a year ago, I switched it over to 0W-40 to take advantage of the better lubrication at startup. I noticed that it got to proper operating viscosity much faster (by watching how long it takes for the oil pressure at idle to drop from over 4 bar to under 2 bar, demonstrating that the oil is flowing through the passages rather than just backing up against the oil pump) and it always developed over 4 bar oil pressure at high RPMs, no matter how long I'd been driving or under what conditions.
However, I just spent Sunday at Sebring and I'm disappointed to report that I'm not satisfied with the 0W-40's performance on the racetrack. I was seeing around 3.5-3.6 bar oil pressure all the way down the back straight even near redline, where I'd like to be seeing nearly 5 bar.
Now I suppose I COULD invest in a larger oil cooler, but I think I'd rather just switch to the 0W-50 before I go back to Sebring. I'll see how that works out and report back...
