I've been an Amsoil fan for as long as I've been driving but I use Toyota 0w20 and Toyota filter in my 2011 4Runner Trail Edition. It's an excellent oil that protects well at start up. It's not much more than conventional oil and at 12,000 miles a year you could get away with one oil change a year. You could do a UOA through Blackstone at 8,000 miles just to make sure
