Special Oil Requirements for Catalyst
Engines
51842
Engines covered by this manual are equipped with
catalytic converters. These catalysts combined with a
system of sensors and computer controls of the engine
are designed to meet stringent exhaust emissions
standards. Proper engine oil quality is critical to the
service life of the catalysts. Oils that do not meet these
specifications may contain excessive amounts of addi-
tives, impurities, and other substances which are
passed through the exhaust and will ignite when they
contact the hot catalyst. The ignition of these substan-
ces on the catalyst will damage the catalyst.
Engine Oil Specifications
Whenever oil is added to the engine, we strongly rec-
ommend the use of Volvo Penta full Synthetic Gaso-
line Engine Oil Catalytic Converter Approved SAE
10W-40. These oils are engineered to meet all of the
requirements of your V8-380 and are formulated spe-
cifically for marine engines. These oils are available at
Volvo Penta dealers.
If the Volvo Penta oil is not available
, use an oil that
meets NMMA FC-W Catalyst Compatible® specifica-
tions. Viscosity should be SAE 10W-40
or higher
(example: 15W-40, 20W-40, 25W-40, 15W-50). Do
not use 0W40 or any XW-30 oils (example: 10W-30).
NOTICE!
Catalyst failure will occur if the wrong oil is
used in these engines. This failure is not covered by
warranty.
NOTICE!
Do not use oil rated for diesel engines in
gasoline engines with catalysts. Compounds in the oil
may ignite at the catalyst, causing catalyst failure. This
failure is not covered by warranty.
NOTICE!
Do not use engine oil additives in engines
with catalysts. Compounds in the additives may ignite
at the catalyst, causing catalyst failure. This failure is
not covered by warranty.
