    Get a fuel sample and put it in a clear glass container. Let it sit for 10 minutes.
    If there is anything but gasoline, you'll see it. Usually, water...
    A large bottle of stp fuel treatment for 2 full tank should clear it out.

    Did you change the spark plugs? Maybe they are fakes?

    Theman414 was last seen in March of 2019.

    The Prius death rattle was in February of that year.
    My guess is that this person is driving another car....and with gas prices being the way they are probably also wishing that they had just fixed the head gasket.
