Thanks Bryan I'm sure you're right. It appears Honda was first by quite a few years specifying the 0W-20 grade. Toyota didn't till I think 2009 for the Prius, the original was spec'd for 5W-30.
The 2nd Generation Insight, Civic Hybrid and Fit models have the so-called 0W-10 Ultra Green as the FF from Japan. This oil is available, likely a non SAE precursor to the Honda 0W-16.
Those that can't wait can get Ultra Green here:
