>From old Porsche experience, we found that different grades of Mobil 1 are
formulated differently. For example, 0W40 is suitable for the flat six
because it has the necessary higher zinc content, while other grades do not
and should not be used. I guess the bottom line is to check the zinc
content of the particular grade you're planning to use. Probably, you will
find this information on the manufacturer's website. Alternatively, check
the open Internet.
Cheers.
