    Any luck slowing oil burning with a stop leak (lucas, blue devil, bars, etc.)

    Is this normal operation for a Prius?

    It did. That pretty much sounds like a good description of what I am hearing.

    I bought a 2009 Prius with 230,000 Miles.

    How do you manage that: filling up with the highest octane (that's often ethanol free), or some independent station?
