Good resource here.

Why would it be worse. That would be entirely interval dependent. Both would perform the same if the intervals were short. Synthetics last longer in service. That doesn't necessarily mean a conventional wouldn't be fine as well.

If your engine was back-spec'd for a 20 grade,and you aren't operating in the "severe service" realm then a 20 grade would be fine.
Millions of engines run 20 grades and they are lasting longer than the car around it does,just consider that tidbit of info.
Go buy the Toyota genuine motor oil in the 0w-20 flavour. Its a Mobil product and we've amassed quite a few used oil analysis here with that oil,and it's proven to be a fantastic product capable of their 10000 mile interval easily in most applications.
I wouldn't even consider any other options to be honest. You've got an oil that's engineered for Toyota engines available and since it's been in use its been tested and talked about to death here,and is a proven quality product.
If it really concerns you using a 20 grade,engineered for Toyota,then substitute a quart or 2 for m1 0w-40.
You end up with a mixture that has a sky high viscosity index,which is good,and the mix ends up having properties combined that are better than what you can buy off the shelf in a 30 grade b
Here it's called the Caterham blend. Use the search function and get comfy. You'll be there all night.
