    So read my receipt and noticed that they put conventional oil in my 2009 Prius at the dealer. Always used synthetic in the past. Strange thing is my MPG went up. Odd. When a Prius gets 95K on it should we switch to 5w20/0w30 etc in warm climates?
    Any real life test results?

    When we put 0 30 in our '10 at 36K mileage went down roughly to 42mpg
