Superior Protection
Against Engine Wear
Marine engines operate under
high loads and RPMs for extended periods of
time, causing traditional automotive oils
to break down and lose viscosity. To ensure
good protection, the NMMA set minimum shear
stability requirements for FC-W. AMSOIL Formula
4-Stroke® Marine Synthetic Motor Oil greatly
exceeds the FC-W shear stability requirements,
outperforming competitive
oils to deliver a superior lubricating film. Formula 4-Stroke® Synthetic Oil also 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. However, good rust protection is
not natural to engine oil. It comes only by
design. Formula 4-Stroke® Marine Synthetic
Motor Oil is fortified with a special anti-rust
agent, even more than required to pass stringent
NMMA FC-W anti-rust testing.
Applications
AMSOIL Formula 4-Stroke® Marine Synthetic
10W-30 Motor Oil (WCT) is recommended for
gasoline fueled four-stroke outboard, inboard,
inboard/outboard (I/O) and personal watercraft
motors. AMSOIL WCT motor oil is recommended
for the following applications whenever an
SAE 5W-30, 10W-30 or straight SAE 30 oil is
called for:
Four-stroke
outboard motors: Honda®, Mercury®,
Yamaha®, Johnson®/Evinrude®, Bombardier/BRP®,
Suzuki®, Nissan®, Tohatsu®
Inboard
and I/O: Mercruiser®, Volvo
Penta®, OMC®, Chrysler® Marine,
Crusader®, Marine Power®, Chevrolet®,
Ford®
Personal
Watercraft: Honda®, Yamaha®,
Bombardier/BRP® (Sea-Doo®), Polaris®
Note: AMSOIL Formula 4-Stroke® Marine Synthetic
10W-30 is recommended for use in place of
5W-30 as specified by Honda®.

Service Life
• Four-stroke
outboard motors and personal watercraft applications: Due to potential fuel dilution or water contamination,
change oil at the engine or watercraft manufacturer
recommended interval.
• Inboard
and I/O applications: Change oil
at two times the engine manufacturer recommended
interval or one year, whichever comes first.
Mixing AMSOIL
AMSOIL Formula 4-Stroke® Marine Synthetic
Motor Oil is compatible with conventional
and synthetic motor oils. Mixing AMSOIL motor
oils with other oils will, however, shorten
the oil life expectancy and reduce the performance
benefits. AMSOIL does not support extended
drain intervals where oils have been mixed.
Aftermarket oil
additives are not recommended for use with
AMSOIL motor oils.
