Formula 4-Stroke® Marine Synthetic Motor Oil 10W-30
(WCT) and Formula 4-Stroke® Marine Synthetic Motor Oil 10W-30 (WCF) are formulated specifically for use in
4-stroke gasoline-fueled engines used in marine
applications. They offer unsurpassed wear protection,
viscosity stability, low volatility and excellent
low temperature fluidity. AMSOIL Formula
4-Stroke® Marine Synthetic Motor Oils meet the
“Warranty Certified” status of engine manufacturers.
They are recommended for use in 4-stroke outboard
motors including Honda, Yamaha, Mercury,
Suzuki, Johnson-Evinrude (BRP) and more. Also
excellent for use in marine inboard/outboard engines,
marine inboard power plants and personal water craft.
Performance Improver Gasoline
Additive (API) dissolves and removes fuel
system deposits and other contaminants for
improved power and overall performance in
fuel injected and carbureted gasoline
engines. AMSOIL PI also reduces PCV and
EGR system deposits, reduces exhaust emissions
and improves engine starting, idling
Gasoline Stabilizer (AST) keeps gasoline
and diesel fuel from oxidizing and deteriorating,
prolonging its storage life. Gasoline Stabilizer
inhibits the formation of varnish and
gum, which helps prevent poor injector and
AMSOIL Engine Fogging Oil’s (FOG)
superior film retention provides stored equipment
with long-term protection against corrosion
and dry starts, extending engine life
and reducing operating expenses. Its aerosol
spray formulation offers easy and clean applications, while
reaching more components and offering complete distribution
of the oil, something especially beneficial in applications
with horizontal cylinder orientation such as outboard motors.
Engine Life Increases 500 Percent
More than 60,000 tourists annually visit
Alpine Canyons, South Island, New Zealand for high-speed thrills on
Shotover Jet Ltd jetboats.
The tourist trade is tough service for the boats.
The Chevrolet 454 cu in V-8 engined jetboats are in service 365 days a year,
making up to 28 high speed river trips a day. The boats develop maximum
torque at extremely low engine operating temperatures, due to the cooling
effect of the snow-fed river water they draw. How does Shotover protect
these hard working engines?
AMSOIL Synthetic Motor Oils and
AMSOIL By-Pass Oil Filters. Before converting the boats to AMSOIL
motor oil and filters and propane fuel, oil change intervals were at 25
hours and engine life in the 500 hour range. The propane fuel, AMSOIL motor
oil and AMSOIL by-pass filter combination provides 400-hour oil change
intervals and engine life up to 2500 hours - that's 16 times greater oil
change intervals and five times greater engine life - a huge savings
for Shotover Jet Ltd.
