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:

Wife just got a new Impala with the 2.2L engine. I have GC and 10W30 Amsoil in stock. 10W30 should not hurt, as we are in Florida, where it is HOT.They specify 5W30 on the filler cap.
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:

Congrats to your bro' on the new truck. I will probably get the 4 banger Colorado when I trade in a couple years after any bugs are worked out. 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.
