Should do well or better for the 1st / 2nd generation with the 1.5ltr. and the 3rd as well . Go here for the report , Used oil analysis of Toyota Yaris ( 1.5 ltr. ) with SHELL synthetic 5w-20 ( S.N.)... | PriusChat .
Blackstone does not do one of the most important numbers the TAN. Total acid number. The one under the TBN. Maybe have to request it. But should be included. That's why I use Wearcheck. There the big boys in the UOA biz. $25 for a oil test: Wear Check International - The Oil Speaks…We Listen…You Save
Wouldn't bother with a TAN with less than 5,000 miles or 6 months on the oil which is implied by Toyota . Thanks for the other oil analaysis company .
