    Hi

    I have a 2006 Prius, had it for a few years, for the past 4-5 months i've been getting poor MPG, around 30MPG locally, used to get around 45-50 locally.
    I took it for a long drive on the motorway and got 50+MPG.... but locally I'm getting no where near what i should,
    The battery is charging, and isnt loosing charge any quicker than it used to 3 years ago.
    I've changed Air filter, Pollen/Cabin filter, oil and oil filter. Changed the plugs around 2 years ago, and have done around 10k since changing, It has low mileage around 105k

    Any ideas why locally I dont get the correct MPG but on the motorway i did?

    Winter time with cold engine = miserable MPG

    In cold weather short trips (anything under about 10 minutes) is a real MPG killer.
