Engine Oil Recommendation in my 986 owner's manual yesterday.

I was amazed to see that 10W30 is actually listed in colder (Below 50F/10C) environments. And then contradicted in bold with a "10W40" or higher statement.

I wouldn't and don't use ..W30 but I wanted to interject this little bit of Porsche's contradictory view into the discussion.

You ought to see the viscosity Honda recommends/uses!
