A small number of customers with Honda, Acura, 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.
To protect the engine, the OEM engineered the oil pressure sensor to trigger the oil light when there is insufficient oil pressure to maintain an adequate level of protection. Each filter is equipped with a by-pass valve, so when the filter is at or close to capacity, the engine is continually supplied with adequate lubrication oil, although unfiltered. However, if the filter reaches maximum capacity, the level of restriction can become significant enough to trigger the oil pressure warning light. In extreme situations, oil starvation can occur. Premature oil filter capacity can be attributed to a number of factors such as poor air filtration, a leaking air intake system or excessive contaminants being produced in the combustion process.
AMSOIL recommends changing the EaO13 Oil Filter according to OEM-recommended intervals in the following applications:
• 2001-2010 Honda
• 2002-2010 Acura
• 1992-2006 Chrysler imports
• 1993-1997 Ford Probe
• 1996-2010 Nissan/Infiniti
• 1971-2000 Mazda
• 1999-2000 Mercury Villager
• 1990-2010 Mitsubishi
• 2004-2007 Saturn
Customers using an EaO13 Oil Filter beyond the OEM-recommended interval in any of the listed applications are advised to change the filter at the earliest opportunity. If the oil light is triggered, change the filter immediately to avoid damage. For more information, see the AMSOIL EaO13 Oil Filter Technical Service Bulletin, or contact AMSOIL Technical Services at (715) 399-8324.
As previously announced, the AMSOIL EaO09, EaO10 and EaO57 oil filters are no longer recommended for Toyota, Lexus and Pontiac vehicles with Toyota-built engines. Dealers should contact any customers using these filters in the above-mentioned applications and advise that the filters be removed. MANN filters are available for these applications, and they are recommended for 7,500-mile filter change intervals when used in conjunction with AMSOIL motor oil. For more information, see the EaO Filters - Toyota Applications Technical Service Bulletin , or contact AMSOIL Technical Services at (715) 399-8324.
