5K miles as per the maintenance schedule with full synthetic oil, and 87 octane per the manual.
Anyone putting higher than 87 in a V6 is just wasting their money. Don't take my word for it, there's plenty of corroborating research.
Could be California gas, but 91 pings a LOT less in both my 4runner and my Tacoma 4.0s than 87 does. I've been running 91 in the Tacoma since I bought it brand new (with 87 once or twice to see if there was a difference) in 2006. I tried running 87 in the 4runner when I first got it just to see and eventually switched it to 91 as well.
