I run 10w30. That's what Dodge suggested for the 360, so that's what it gets.
Just the cheap stuff. Supertech from WalMart is usually what goes in, but then I find a quality filter. No Fram, ever.
I change the oil when it looks like it needs it or if it begins smelling like fuel. That means the oil was changed by my grandfather in the 90s, then I changed it last month. In the meantime, it was started a few times in 2010 after sitting for over a decade, then started a few times in 2015, then started and driven 60 miles this year. As I have not really used it, I kept the old oil and filter.
This year will be different, though... I'll probably change it again in the fall, as I am actually driving it weekly (not much, just 3 miles from storage to the house, and another 3 miles back every weekend), but we'll be taking it to White Sands next week (55 miles each way), and a couple short-ish trips to work out the bugs (100 miles each way or so), before using it on a medium distance (150 miles), 2 week boondocking trip in the mountains in July. After that, we'll try to get out in it about once per month for the remainder of the year.
