  1. How is your experience with HIGH cases Prius 2010-2015, 3rd gen Prius head gasket? I heard 2013-up has revised head gasket and has less issue. Especially 2015-up with updated piston and piston rings. Is it true that 2015-up 2ZR-FXE engines are much better than the previous year?

  2.  @TheCarCareNut  Does it have to be 4th gen or just the last 3rd gen is much better? In Europe Corolla IM hybrid, 2013-2018 is sold 8x more than Prius. However, we do not have widespread head gasket problems. Is it possible because the minimum in EU is Super95 5% Ethanol or 90midgrade in USA grade octane fuel? I remember that my Prius 2nd gen has light pinging ing light load with regular E10 when I lived in FL. It does not do that before 2008 when we still use pure Gasoline, not E10 in USA. I feel like cars made before 2008 are tuned for non-ethanol fuel and E10 causes slight lean and light pinging under Light Load/close loop. My Camry 2002, Altima 2002, Sienna 2004 all had pinging issues under light load.
