Product Description: AMSOIL EaO47 Oil Filter
Subject: The EaO47 is not recommended for Suzuki/GM 3.6L V6 engine applications.
OBJECTIVE:
Define the new application recommendations for the EaO47 Oil Filter.
ISSUES:
Laboratory and field analyses have concluded that the Suzuki/GM 3.6L V6 engine found in several 2007 and 2008 GM and Suzuki vehicles has unique internal characteristics that prevent the EaO47 Filter from functioning properly.
TECHNICAL DISCUSSION:
The unique design of the Suzuki/GM 3.6L V6 engine is not compatible with the design of the EaO47 Filter. However, the design incompatibilities are limited to this particular engine and do not apply to other engines to which the EaO47 filter applies.

AMSOIL recommends the WIX 57060 oil filter for Suzuki/GM 3.6L V6 engine applications.
