To the Mobil 1 enthusiasts:
You do know that Mobil 1 is a significantly different formulation now than when that sticker was attached don't you? Check BITOG for details.
And since that sticker was attached as a joint marketing enterprise between Porsche and Mobil, many new ,different & better(?) oils have been introduced.
And the long term lubrication issues of the M96 are better understood than they were 15 years ago .
So sticking with such an old recommendation may not be the optimum choice?
