I was wondering what is a good weight of oil to use. I have a 5.3L w/true duals and I live in the south where it is hot most of the year. From what I understand, 5w-30, what I'm running now, is good for cold weather. I was wondering if it would be beneficial to switch to a heavier oil. Please let me know.

Thanks,
John

I use Mobil 5w30syn in the winter and the 15w50syn(perfomance driving formula)in the summer. 15w50 seems a little thick when you hear it but since its fully synthetic and it flows very easily.

I use amsoil 10w-30 year round,My book says to use 5w-30 but I think its just a little to thin for 100+ degree heat hear in texas.

exactly what he said, and with the thicker oil you wont have any problems burning oil. i ran 15/50 all last year, i'm gonna go to 5/30 this winter just for the hell of it though, probably around november since it's so warm most of the year down here anyways, and back to 15/50 around march.
