It is an approved oil, so the oil doesn't have much ZDDP in it. Too much is bad. Why? Well... MarcW - Friday, 22 April, 2011, at 5:52:29 pm |

True. But the point is the opposite of that. No non API or ACEA oil is approved. grant - Sunday, 24 April, 2011, at 8:03:04 pm |

The whole point of this discussion is that political pressure in the form of regulations and monetary penalties has caused automakers to alter their recommendations so they have. Oil company's have also altered their formulas. That's not to say the new oil is not good it's just not the best. You are sacrificing the parts when contact occurs to save your planet. Now it is very unlikely that any of the wear cause by the lessor oils will cause a problem while the car is under warranty so a valve train problem will belong to the cars owner not Porsche.
The brands recommended by the writers at Excellence are recommended because they are in the owners best interest not the planets.

which I guess means if you believe the people advising you do this know more about the car and its engine and its oiling/lubrication requirements than the people who designed, built, and warranty the car you bought.
