I would say a synthetic oil would be best. But the question is whether or not the Yaris would benefit from it. I had a high output turbo motor that I used synthetic on because of the extremes the engine went through. Its more stable at high temps and whatnot.

If you have ever seen the innards of an engine that used synthetic you would see that it actually impregnates the metal so that you will see the staining . Its pretty cool stuff.

I would think that a Yaris that is driven in a way it was designed for would never actually need the benefits that synthetic gives. Meaning, by the time the engine is worn out (using regular oil) the car would have soo many miles that the chassis would be worn.

I think that article pertains to older type and racing motors that have no direct connection to new/oem built motors.

Its an interesting article none the less.
