5w30 is a little thinner, so its better in cold weather for starting up.I use Mobil 1, but I use 10w-30... I'll be using 5w on my 2nd upcoming oil change (i already got 6 quarts on sale of 10w-30. LOL) Manual says 10w is recommended. Any reason why everyones usin 5w? Cold weather areas?

It doesnt. It clearly says 5w30 in my manual. Im looking at it now...i didnt know that the 3.6 says to use 10w30...
Where did anyone say Mobil 1 was the best? They simply said it was recommended, so thats what they use. Also, show me a 1st gen CTS with the DI engine.If you think Mobil 1 is the best oil for the 3.6 L engine in the CTS you'd better think again. The 3.6, especially in its DI version, has been proven to be especially hard on oil and the UOA for Mobil 1 has been way less than stellar.
We also have a 2008 Buick Enclave with the newer version (NOT DI) 3.6 and there's been a ton of information posted on Enclaveforum.net. Pennzoil Platinum, Pennzoil Ultra, and Castrol Edge have all shown good UOA results with the 3.6 DI engine. I'm using either Pennzoil Platinum or Ultra since it's available at Walmart and is a little cheaper than Castrol Edge. Pennzoil Platinum has also been certified to the new GM Dexos oil specification that must be used in all 2011 GM engines.
I personally find that I like the new pepsi vs the pepsi throwback (with real sugar).oh dear lord, another pepsi vs coke thread
I agree but it made me think... If I don't like the real sugar... wtf is the stuff I'm liking now?throwback is for the birds. That stuff is nasty.
