Changing Engine Crankcase Oil
Due to recent EPA mandates on internal combustion engines new units
are built with catalytic convertors installed in the exhaust manifolds,
along with a system of sensors and computer controls. These newer
engines require special oil requirements to extend the life of the
catalysts.
Refer to the MerCruiser engine operator’s manual for the correct oil
requirements for catalyst type engines, or contact your nearest Regal
or MerCruiser dealer for further information.
For other engines not manufactured as catalyst engines refer to your
engine operator’s manual for correct oil recommendations.
