Maybe he knows more than the Porsche co-marketing folks
who set up the deal to give Mobile all the promotion (in exchange for what?).
How are we sure this co-marketing deal is for the benefit of customers or not just another deal that provides kickbacks?
If it was just in a TSB where their recommendations were, I'd be more inclined to believe it was engineers speaking.
Let me suggest that Porsche probably gets all their oil and certainly gets the benefit of Mobile advertising the Porsche exclusive-use. Every time Mobile says the word "Porsche" in an oil commercial, Porsche marketing benefits.
And those who analyze the internals of Boxster engines that have failed or are beginning to fail seem to agree on one thing...that the oil recommendations that Porsche has made and continues to make for the M96 engines are not the right way to protect the engine based on their analysis of hundreds of engines and the contents of their oil over several years.
And many say not to use Mobile 1 and recommend a thicker base viscosity.
Can JFP be right in thinking that the Porsche engineers choice is suspect too?
My next change won't be 0W40 and won't be Mobile 1.
