We have a Ford F150 Ecoboost in the family now and the owners manual had an addendum in it specifying an oil filter change to the new FL 2055. The engine had a much smaller filter on it from the factory. Ford even specifies that warranty requirements dictate the use of this filter. OK, changed the oil on the truck last week using this $21 filter and Motorcraft Full Synthetic oil and now I read this: FORD AUTHORIZED DISTRIBUTOR BULLETIN #11-049 To: (X) Motorcraft Warehouse Distributors ( ) Powertrain Distributors ( ) Motorcraft Battery Distributors ( ) Motorcraft Bulk Oil Distributors ( ) Accessory Distributors Date: April 29, 2011 Subject: Stop Sale on FL2055 Oil Filter; Replaced by FL500S Questions: Aftermarket Zone Manager FL2055 REPLACED BY FL500S FCSD has issued a Stop Sale & Return on the FL2055 Oil Filter for the new 2011 F150 EcoBoost engine. · Ford Engineering Teams identified fit issues in using the FL2055, and have decided to discontinue this part number. · The FL2055 has been replaced by the FL500S (Service Part Number AA5Z-6714-A/FL500S). · Ford Dealership Parts Managers were notified of the change through DOESII message # 3593 on April 28, 2011. · Ford Cataloging systems will be updated in the weeks that follow. · The affected parts should be returned per the claiming instructions below.
