    So yesterday in the mail I got this notice from Amsoil:

    "Dear AMSOIL Customer:

    Our records indicate you have purchased an AMSOIL Ea009 or an Ea010 oil filter within the last year.

    Please be informed the recommended change interval has changed for the Ea009 and Ea010 Oil Filters used with any Toyota/Lexus application, or with the Pontiac Vibe featuring the 1.8L engine built by Toyota.

    AMSOIL now recommends changing EA009 and Ea010 Filters used int he above-listed applications according to the filter change interval recommended by your vehicle manufacturer. Refer to your owner's manual. Customers operating with any of the above-listed applications with an Ea009 or Ea010 Filter in service beyond the vehicle manufacturer's recommended interval should change the oil filter at the earliest opportunity. If the oil light is triggered, the filter should be changed immediately. For more information contact AMSOIL Technical Services at (715) 399-TECH or tech@amsoil.com.

    Sincerely,

    AMSOIL Corporate Communications
    AMSOIL INC.
    Superior, WI 54880"

    Did anyone else get this notice? It's making me question if I should even keep the oil in for the extended interval. I have about 7,000 miles on this filter.

    I found out some more information. Amsoil sent out a TSB about this issue. The exact wording is below:
    Quote:
    OBJECTIVE:
    Inform customers of an issue regarding the oil sensor tripping
    in the following applications:
    • All Toyota/Lexus Vehicles
    • Pontiac Vibe Featuring the 1.8L Toyota-Built Engine.
    ISSUES:
    A small number of customers with Toyota, Lexus and Pontiac
    vehicles with Toyota-built engines have reported that
    their vehicles’ oil pressure light has illuminated prior to
    reaching the end of the AMSOIL-recommended 25,000-
    mile drain interval.
    TECHNICAL DISCUSSION:
    To protect the engine, the OEM has engineered the oil
    pressure sensor to trigger the oil light when there is insuffi
    cient oil pressure to maintain an adequate level of protection.
    Each fi lter is equipped with a by-pass valve, so when
    the fi lter is at or close to capacity, the engine is continually
    supplied with adequate lubrication oil, although unfi ltered.
    However, if the fi lter reaches maximum capacity, the level
    of restriction can become signifi cant enough to trigger the
    oil pressure warning light. In extreme situations, oil starvation
    could occur.
    Premature oil fi lter capacity can be attributed to a number
    of factors such as poor air fi ltration, a leaking air intake
    system or excessive contaminants being produced in the
    combustion process. As discussed in the AMSOIL Technical
    Service Bulletin Using AMSOIL in Engines with Possible
    Sludge Issues,1 certain engines are prone to accumulate
    sludge, including some engines from Toyota/Lexus.
    RECOMMENDATION:
    When used in conjunction with any Toyota/Lexus application,
    or with the Pontiac Vibe featuring the 1.8L engine built
    by Toyota, AMSOIL recommends changing EaO09 and
    EaO10 Filters per the OEM-recommended change interval.
    AMSOIL no longer recommends the EaO57 Oil Filter
    for Toyota/Lexus applications, however, it is still recommended
    for other applicable vehicle makes and off-road
    equipment. Customers operating any of the above listed
    applications with an EaO09, EaO10 or EaO57 Filter in
    service beyond the OEM-recommended interval should
    change the oil fi lter at the earliest opportunity. If the oil
    light is triggered the fi lter should be changed immediately
    to avoid damage. AMSOIL also offers WIX Filters as an alternative
    to the Ea Filtration line and recommends the WIX
    51348 Oil Filter for Toyota/Lexus applications that previously
    called for an EaO57 Filter. If a WIX Oil Filter is used,
    AMSOIL recommends changing it at OEM-recommended
    intervals.
