Use Synthetic oil on 2007 sienna?

The 2013 can ONLY use synthetic and gets changed every 10K.
I have a 2007 4Runner V8 in which I have always used synthetic.
I had a new 2002 Camaro and that LS motor came with Mobil 1 in it from the factory.
Full synthetic has better lubricating qualities and lasts longer.

Synthetic oils are more consistent (hydrocarbon molecule chain length) and hold their grade rating better. There should be no issues with using them in your 2007. Maybe overkill for how that motor was manufactured (state of the art in surface finishing 12 years ago), but no downsides that I am aware of save for possibly one....
There is a belief that synthetic oils are more likely to 'find' leakage paths than conventional oils. Not necessarily create, but find seals that aren't is good as they were.
So, my story: I switched on my second or third change to Synthetic back when my 2002 Subaru was near new. It seemed to quiet some of the cold start piston slap those engines were famous for, so I was happy. By 2013 or so it leaked externally like a sieve. Yet the engine ran like a top. Smooth and sweet. A local Subi specialty shop told me to ditch the Mobil 1 (it had done it's job protecting the innards) and switch to a High Mileage oil, preferably conventional. HM oils reportedly include some seal swelling chemistry. I changed to basic Walmart stuff and within a few weeks many of the wet spots dried up. Ran that Outback for 3 more years and sold it to a local used car lot.
Yes, anecdotal confirmation of legend.... Take it for what it's worth.

Uhmm . . . Why would you want to use a 5W-20 oil, be it synthetic or not? Are you in an extremely cold climate that requires such a light weight oil? There is no issue with using synthetic oil, but you would do well to keep it in the recommended weight range for the environment in which you will be using it (i.e. typically 5W-30). For the record, I use 5W-30 Mobil 1 (synthetic) with very good results. I also have some leftover 5w-20 Mobil 1 that was for my daughter's Honda (now sold), but I would not put it in my Sienna unless I literally had no other choice available.
