    '07 has dropped from 50 to 40 mgp in about 3-4 weeks time??
    Also it makes a weazing noise when shut off- this too started small and has gotten worse as milage dropped- any ideas?

    The outside temperature can account for the drop in mileage. The noise is probably from the thermos tank pump which tends to get noiser in colder weather (at least that has been my experience with my '04 and '09).

    Had ours for 2 years now and can only get 45 mpg at best. Although pretty hilly here in the northwest.
