Special Oil Requirements for Catalyst
Engines
51583
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. Volvo Penta requires
engine oil with API SM and/or ILSAC GF-4 specifica-
tions for all engines equipped with catalytic converters.
Oils that do not meet these specifications may contain
excessive amounts of additives, impurities, and other
substances which are passed through the exhaust and
will ignite when they contact the hot catalyst. The igni-
tion of these substances on the catalyst will damage
the catalyst.
Engine Oil Specifications
51584
Whenever oil is added to the engine, we strongly rec-
ommend the use of Volvo Penta gasoline engine oils
approved for catalytic converters. These oils are engi-
neered to meet all of the requirements of your catalyst
engine and are formulated specifically for marine
engines. These oils are available at Volvo Penta deal-
ers.
If the Volvo Penta oils are not available, use high qual-
ity oil that meets API SM and/or ILSAC GF-4 specifi-
cations. Viscosity should be SAE 10W30
or higher
(example: 10W30, 10W40, 15W50). Straight 30W oil
is also acceptable if it meets the API SM and/or ILSAC
GF-4 specifications. Do not use 0W30, 5W30 or any
20W oils (example: 5W20).
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.
