I just learned this is the oil that was put into my 2012 Prius. It's full synthetic 0w20. The Acura / Mazda dealership buys it in bulk and evidently if it's good enough for Acura and Mazda cars it should be good enough for my Prius. If this is good I should be all set until about late December of this year. I only drive up to about 5000 miles per year.
