Subaru Ascent towing 4,400 pounds
The cart before the horse theory, I guess. My soon to be SIL bought a new Subaru Ascent. Then he went out and bought a 4,400 lbs non-slide trailer. My first though was "A four banger towing a trailer?...

Factory recommended oil on that turbo Ascent is 0W-20. Not sure I’d want that towing.
That's a new one on me. Care to cite any documentation that may support your assertion?
0W does not mean "zero lubrication." It simply means it is a very thin oil at room temperature. The tolerances in the engine are extremely tight, requiring that grade oil.
That said, the 8.1L in my Chevy 3500 specifies 5W-30 and is rated to tow something like 14,000lbs, and I would not have any qualms about pulling 16,000+ with it. The oil is not THAT much thicker.
