I personally do the Toyota recommended 5,000 mile interval (I may stretch it to 5,500) and just use regular oil.

Synthetic is nice, but expensive, so it's up to you. I just don't think it's necessary on a car like the Yaris. Typically though, you can certainly go longer between changes with the synthetic so it may balance out in costs somewhat.

There's not much hard evidence as far as engine longevity.
