ATTN: FP Red & Black Users - What You Need to Know About Oil
2010 Porsche 911 Turbo:
Mobil 1 0w-40
(I'd be curious if the 911 gt2 rs takes the same)
Ford GT:
Takes 5w50 motorcraft oil for the GT (XO-5W50-QGT) which meets specification WSS-M2C931-B.
Ferrari Enzo:
Takes 10w-60 Shell Helix oil at a whopping $61.59 a quart. The Enzo takes about 11 quarts of the stuff. If you do not use the "special" oil Ferrari recommends then, the warranty on the car is voided. Total price for a Ferrari dealer oil change is $1200.00.

The higher viscosity oil is more forgiving in a situation where the heat is sufficient to cause a lower viscosity oil to lose film strength under extreme temperatures - such as what is possible when those two steel bushings are forced together at very high pressures and shaft speeds. But where this is the case, a full synthetic (of the proper viscosity) becomes even more advantageous.
Min Levels of ZDDP ???
Correct me if I'm wrong, but after reading the threads I see the number of 1000ppm as the borderline of what is acceptable or not, without entering in the additives/detergents/modifiers/viscosity side of the issue.
But then comes the FP document an throws that away with a frontier of 1200ppm, but even in the document an oil with that number is not accepted and another is. Maybe is time to ask Robert@FP and if he allows, post his response here.
I'm no oil expert and respect all the knowledge that people like you, TedB and others have provided. It's my opinion that these threads have taught a lot to many people in this important matter, bringing knowledge where uniformed advice is mostly given at the decision time.
So what would the consensus be? 1000, 1100, 1200, 1300?
Best regards to all
Just did an oil change with their 10w30. It isn't full synthetic, still has some detergents and they had a dealer down the street from me. I change my oil regularly at 3k but will do it a little bit earlier to be on the safe side

After quite a bit of trying I finally made contact with an actual motor oil scientist on the friction modifier question.
I knew that Amsoil AMO doesn't have them, and had a feeling that the Penn Grade 1 and some of the other oils don't either.
So the question was, why don't they?
Here is what he said:
When he says "Friction modifiers compete for surface area" he means they compete with ZDDP for surface area on your bearing surfaces.

Here is what he said:
There is a modest amount of friction modifier built into the main detergent inhibitor package that is utilized in our PENN GRADE 1 oils which affords favorable sequence VI-6 fuel economy test results in ILSAC SAE grade 10W-30. A formulator may add additional friction modifier to lighter oils such as 5W-20, and 5W-30 due to tougher test requirements for these grades. Additional friction modifier added to the 20W-50 grade would offer no benefit in the sequence VI fuel economy test because the kinematic viscosity of this grade is much too high to attain fuel economy benefits no matter how much friction modifier is added, similarly for grades 10W-40 & 15W-40. Friction modifiers compete for surface area, too much and anti-wear performance may be compromised.
ZDDP is a time proven additive that has several functions: Antiwear agent due to the formation of chemical reactions on metal contacting surfaces resulting in a lower shear rate than the base metal, Antioxidant, Rust and Corrosion Inhibitor – acts as a peroxide inhibitor which is a precursor to carboxylic acid formation. Engine oils will also employ dispersants and detergents to combat sludge, varnish and neutralize any acids that are formed. The sole function of friction modifiers is a very modest gain in fuel economy. Friction modifiers have a legitimate place in engine oils and have helped save many gallons of petrol, not to mention many dollars for car manufacturers helping them meet Corporate Average Fuel Economy limits (not sure what the fine is today), hence the drive towards lighter oils 0W-20 and 5W-20.

^^^^^ Same here. Installed it last night JIT for my BBK Full and GSC install tomorrow! Might be imagining things, but the engine at least seemed quieter mechanically upon start-up this morning, and I saw a slight bump in oil pressure at idle on my DEFI gauge.

Just because it says 'racing' - doesn't make it better. Especially for street/strip use.
