I use and recommend Mobil 1 in most of my rigs and change oil once or twice per year. That being said, I run Rotella T6 in my landcruiser and change about every 8 months or so.
That being said, if I was you and wanted synthetic, I'd run Mobil 1 and if I wanted dino, I'd run Chevron. Both are available at Costco and Walmart, etc, in larger bottle sizes.
I'd probably use 5w-30 or 0W-40 in lieu of the 0W-20, but as mentioned, everybody has an opinion on oil, and if you want your head to spin, go to the "bobistheoilguy.com" web site and see what the real fanatics have to say......
