JB, I'll give you the benefit of the doubt, that you are legitamately interested in my position and simply want some physical evidence of my claims. No problem, I completely understand.
In 2 parts, my case is that M1 15w-50 is not what is actually used in real race cars. I think I have gone a way toward doing that already, it is a charade to boost M1 sales while giving custom-blended Mobil "1" componets to the sponsored teams. The reason there is so little feedback on this is the non-disclosure agreement that comes along with a sponsorship contract. End of story.
Secondly, when you get guys hod-rodding on M1 "racing", believing it is up to the mega-horsepower applications alluded to in NASCAR, it falls flat on it's [****] .
That is my "theory" and how I "prove" it is the same way it would be proven in court, through the testimony of a recognized expert. Is BitOG going to draw out all the facts that a court case would, no. It costs money to tear-down an engine, but if you want to pay my mechanic, he has a few of the exact engines in question. Probally he would give a technical report to you as well, if you paid for it. I took a bunch of the guy's time to get the story, and WE are going to have to settle for that. JB, you KNOW that I was not out trying to give a constant lecture on this and prepare some bush-league "court case" for the benefit of everyone. (who will never be convinced and will peck at me constanty anyway) If that is your standard, sorry, no UOAs...I don't need them, I know who I am talking to. Again, this grew out a request of oil advice for a 944T, I gave him very good advice. If you are so interested, send me a Blackstone Kit and I will sample the probally fresh M1 in a blown Porsche engine for you. Nothing special will be apparent in the UOA, I don't think that is the question. I actually hoped someone here would know why, for instance, M1 15w-50 does so poorly in a 4-ball test. Maybe it is akin the the tires that break away without warning verses ones who loose traction progressively. Both have the same traction rating, like Mobil and Castrol both meet SAE 50, but the oil film does not blow out as easily in one as the other. That would be an area of investigation, imo. My guy specificly said: "under the same extreme conditions, the Castrol cars do not blow and the Mobil ones do".
Pretty strait-forward. You want ME to do a finite analysis on the engines and oil, outta my league.
Believe me, you probally don't have to ask too many (independant) Porsche mechanics about this until you hear the same story again. I am actually DONE on this subject, excepting more PMs of support.
