AMSOIL Synthetic Marine Engine Oil is a premium-quality
synthetic formulation engineered for the harsh operating conditions
of marine environments. It withstands the intense mechanical action
of continuous, high-rpm operation to deliver superior viscosity protection.
Synthetic Marine Engine Oil is specially fortified
with a heavy treatment of advanced additives that protect motors against
wear, rust and deposits. It excels in high-horsepower applications and
all-day trolling conditions.
Synthetic Marine Engine Oil is certified by the National
Marine Manufacturers Association (NMMA) for use in four-stroke
outboard motors. This high-quality oil demonstrates outstanding
performance and meets the NMMA FC-W Catalyst Compatible
- NMMA Registration #FC-00358P 10W-30
Superior Protection Against Engine Wear
Marine engines operate under high loads and rpm for extended periods of time, causing
traditional automotive oils to break down and lose viscosity. To ensure protection
and long-term durability, the NMMA introduced the FC-W Catalyst Compatible standard,
which is backward-compatible with the recognized requirements of the FC-W
standard. AMSOIL Synthetic Marine Engine Oil meets the FC-W and
FC-W Catalyst Compatible shear stability requirements, outperforming competitive oils
to deliver a superior lubricating film. Formula 4-Stroke Synthetic Oil contains robust
anti-wear additives that further reduce wear in metal-to-metal contact regions.
Excellent Anti-Rust Performance
Marine engines are prone to rust, leading to uncontrolled wear and premature engine
failure. Good rust protection is not natural to motor oil; it comes only by design.
Synthetic Marine Engine Oil is fortified with a special anti-rust agent,
even more than required to pass stringent NMMA FC-W and FC-W Catalyst Compatible
AMSOIL Synthetic Marine Engine Oil is
recommended for gasoline-fueled four-stroke outboard,
inboard, inboard/outboard (I/O) and personal watercraft
motors. Use the appropriate viscosity grade where specified
in the following:
Honda®, Mercury®, Yamaha®, Johnson®/Evinrude®, Bombardier/BRP®, Suzuki®, Nissan®, Tohatsu®, OMC®, Volvo Penta®,
Mercruiser®, Chevrolet®, Ford®
Note: AMSOIL Formula 4-Stroke Marine Synthetic 10W-30
is recommended for use in place of 5W-30 as specified
- NMMA Registration: 10W-30 – FC-W (CAT)® Registration Number: FC-00833T
- Four-stroke outboard motors and personal watercraft applications: Due to
potential fuel dilution or water contamination, change oil at the engine or watercraft
- Inboard and I/O applications: Change oil at two times the engine manufacturer
recommended interval or one year, whichever comes first.
AMSOIL Synthetic Marine Engine Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil's life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have
Aftermarket oil additives are not recommended for use with
AMSOIL motor oils.
