    2007 Prius
    Model:
    Two
    Every 1100 miles it's burning 1 quart.
    Using Synth blend 5w30 quaker state.
    Change oil every 2500 miles but top it off every 1000 miles. Since it burns oil I am getting p0420 ~2 times every oil change.

    Gives 42mpg.
    Changed pcv, spark plug, vc gasket.

    Should I change oil ? Maybe to full synthetic ? Or should I go for 10w30 ?
    Any suggestions from senior members here ?
