I just got a 21 Prius prime. It has the 2zrfxe engine.
Owners manual recommends 0w16, my question is would 5w30 Pennzoil synthetic be a better choice for longevity?
In the manual it states " an oil with a higher viscosity ( one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions."
I'm not concerned about losing a few miles to a tank of fuel. I just don't want to put oil that is too thick if it may hurt the engine. I have read other countries allow thicker oils for the same engine, I don't know if the US model prime has a different oil pump that only will work with thin oil.
