Synthetic Oil for Towing?
I have a 2007 Chev 2500HD 6.0L gas with 36K Are there any benifits of using say Mobil 1 5w30 synthetic for the towing season? Or is regular 5w30 just as good?

That being said, my new Ram is supposed to use 5w20 oil, which I will certainly use.
Your sig doesn't state if you have a 1500 or 2500, but I don't think the 8 speed is a 2500 option. Thou I don't see buying a new 1500 with a trailer of the size/weight in your sig.
The 2500 with a 5.7 recommends 5w-20 under 14K GCW. Above 14K GCW it calls for 5w-30.
Either way with a 7K+ lb trailer I would be looking at 5w-30, Dodge wants a heavier oil in the 5.7s that work. The lighter oil is for increased economy, but it doesn't protect as well under continuous high power use.
