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.
I need to update the signature...sorry
I do, in fact , have a new 1500....I had a 2500 and hated the ride for a daily driver. When I owned the 2500, I called Chrysler and they said I could run 5w30 with no issue since I did NOT have the MDS engine. The MDS feature that shuts down cylinders absolutely requires 5w20.....again, directly from Chrysler.
I had a.2005 F250 with a V10, a Ford required 5w20 there also....in over 120,000 miles of tough hauling, I got terrible mileage but never any engine issues....I often expected.it would be a quart low, but it never was......
