I found the sticker they put on my window - and it says to use 5w-20....LOL

My salesman was great - Jackie Bowers - and the deal i got was very fair so i don't have any problem there.

Okay - page 555 in the owners manual states:

5.7 L V8 (3UR−FE) engine
SAE 5W−20 or 0W−20

SAE 5W−20 or 0W−20 engine oil may be
used. However, SAE 0W−20 is the best
choice for good fuel economy and good
starting in cold weather
