One thing is I do not want to be responsible for someone causing damage to something because of my opinion.

I especially learned, do not make recommendations based on my opinion, as my opinion is just that, an opinion.

Where is your evidence proving Shell 5w-40 is a better oil than engineers tell an owner to use in a Porsche, used in all around driving?

This is from the LN Engineering site; IIRC, the article is from a magazine in the UK.

Anyway here is the thread link:

Both Mobil 1 and Shell helix don't come out too well in these tests. Penzoil did pretty well for an inexpensive oil; Castrol Syntex wasn't tested. Red Line was one of the top oils mixed with a few that didn't sound local to NA.

I'll let the experts discuss the merits of the test methodology.
