Exactly.

One issue that is hardly discussed is no matter what kind of synthetic oil you use, the filter still should be changed as often as with dyno oils and all the contaminants from blow by, etc still build up.

Synthetics may be a bit better for a high performance engines but are a waste of money for an econo engine like in the Yaris....IMO.
