Really, any xW-30 or xW-20 will serve you well in this engine. My personal preference is for an xW-30 weight. Consider a UOA for extending the OCI if going synthetic. I got a copy of someone's UOA on their '04 Sienna with the 3MZ-FE run under similar conditions to mine, and he's doing 15,000 mile OCIs on M1 with no problems. Too long for my comfort, but I also know I can exceed the 5,000 mile OCI specified by Toyota.
Yea, I would definitely get a UOA if I went any farther than 5K really. I'd like to get one the first time I try to run 5K since they've used conventional and changed it every 3K. I definitely couldn't go 15K in any of my vehicles. I'm a worry wart and it would drive me insane. Haha. What's your oil of choice after running all of those? Have you had any issues with your's using oil?
