Thanks guys. I am debating between the Mobil 1 and Amsoil Signature Series. This is from Amsoil website..

"Original equipment manufacturers (OEMs) like GM* have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. Signature Series Synthetic Motor Oil achieved 100 percent protection against LSPI1 in the engine test required by the GM dexos1 Gen 2 specification - zero occurrences were recorded throughout five consecutive tests."

I'm not sure the difference between Dexos1 Gen 2 vs the Dexos requirement on the vettes and ZL1 1LE's. Any insight on this?
