I use 10w40 down here since we don't get really cold and it gets so hot during the summers. If I was back up north I'd probably use the 10w30 or 5w30 weight. Currently I have no LS motors, but use the same stuff on the ole Dodge 318 I am currently using as a DD.

If the 40W hot doesn't cause you problems I believe my next oil change will be to Shell Rotella T6 5W40. I run that in the tractors so I have a 55gallon drum of T6. I run it in the Jetta and my other machines. Just being conservative on the LQ4 truck and LS4 Impala by running the exact API weight specified.
