Not sure if serious. If you're putting 6 quarts in an S52 you are at high risk of OIL STARVATION. OEM spec is 6.9~ quarts. 7-7.2 is fine.
And Pennzoil is garbage? Since when? Do you know anything about Platinum Ultra? Have you read oil analysis and OCI's on it? It's great stuff, equal to or better than Mobil 1. It can also be gotten in Euro formula, but 5w-40 or 10w-40 would be fine for an S52 (hell, even 10w-30 would be fine, we live in SoCal...)
I run 10w30 Pennzoil Platinum Ultra in my Evo and its engine undergoes quite a but more stress than most S50/S52's. ;)
