When was the last time you read an updated Oil TSB from Porsche?

Do you disclose to your customers that you are using outdated unapproved Porsche oils? They deserve to know and be informed.

After 35 years or so of turning wrenches on these cars, both in successful racing applications and on the street, not to mention running my own shop; I have learned a more than few things that Porsche’s accountants forgot to, or wouldn’t allow their engineers to do.

Your high regard for what passes for TSB’s is more than just humorous, it is completely misguided; as over the years Porsche has so often reversed themselves, particularly when it comes to oils. Their oil brand of choice is a hollow shell of what it was when Exxon took Mobil over in 1999; which is why anyone with a modicum of knowledge on the subject stopped listening to their recommendations years ago. Add in our data base of literally hundreds of oil analysis collected from our own and customer’s cars and it became obvious that both the “recommended” weights and brand had become total nonsense.

As for “disclosing” to our customers that we use what you describe as “outdated and unapproved oils”; perhaps you would be interested in how many Porsche owners switched to our shop (even driving considerable distances to do so) when they hear that our test results show a better pathway…………… So, as the direct result of miscreant and devious ways, we find ourselves having to turn work away because of the line of cars outside the door………..

Blah...blah...blah...blah...blah.....you did not answer the questions. I would assume the answers are, "no".

With you higher base of knowledge, you owe it to forum members here and your customers that your advice goes against the grain of Porsche, so those less knowledgeable than you can make an informed decision ....to believe a trust mechanic (yes, I am sure you do good work! )...or the folks who built the car and continue testing & improving.

Actually, I did, but you did not, or chose not to comprehend my answer…....my customer's know exactly what they are getting.

As for what I “owe” members of this forum, I have openly participated in multiple discussions, here and elsewhere, on the subject of oil performance in the M96 engine for several years. And I am hardly the only one to dispute Porsche’s oil choices on this forum (and others) for many years as well.

Please, feel free to “trust and believe in” whomever you please; as for me, I’ll remain circumspect about the “recommendations” of the engineers that delivered the M96 with the IMS issues, the RMS problems, the slipped sleeves, the “D-chunking”, sintered metal oil pump drives, etc. etc. etc………..
