The owners manual says to use 5W-30.There is a lot of valve train to worry about in this engine.Puts out 220 HP from a 3.5L 5 cylinder engine.My brother just got it in a new GMC Canyon.So far he likes it very much.
Thanksquote:

That's not a terribly high state of tune. The 3.5 V6 in my Chrysler 300M puts out 253 HP. Chrysler specs 10w30, but I'm currently experimenting with Pennzoil 5w20. Expect a 3000 mile UOA on this sometime in June.quote:

It gets below zero for a couple of days around here but nothing really serious.In summer it gets hot but not really bad..I think he is going to go with Mobil 1 in 5W-30 due to the fact he has used that brand in the past and liked it's performance and Wal-Mart here sells 5 Litre jugs of the stuff at a great price..$28 Can...I use the Delvac 5W-40 in my Jeeps.The "off-Road " package was an extra $2000 and is all bling-blingquote:

I would definitely go with 5w30 in this motor and the semi-related 2.2 Ecotoec in our Cavalier seems to like Havoline dino just fine. How cold is winter in Windsor? I can get away with using dino all year.
