Praises AMSOIL!

LNG
Publishing Company, Inc.
In the March 2003 issue of
Lubes 'n' Greases,
Automotive Editor David McFall wrote an
in-depth article on the subject of extended oil drain intervals and
touted AMSOIL as a safe, cost-effective and environmentally preferred
choice. He praised AMSOIL for their commitment to excellence and labeled
AMSOIL "unshackled"
for never conforming to industry norms and standards.

AMSOIL 10W-30 Motor Oil and ten
competing oils were subjected to a series of tests. AMSOIL
outperformed all the competitors in nearly every test! See the
impressive test results!

Certified by the National Marine
Manufacturers Association (NMMA)
AMSOIL Formula 4-Stroke® Synthetic 10W-30 and
10W-40
Marine Oils are a
premium quality synthetic formulation engineered for the
harsh operating conditions of marine environments. They
withstand the intense mechanical action of continuous,
high RPM operation to deliver superior viscosity
protection. AMSOIL Formula 4-Stroke®
Marine Oils are specially fortified with a heavy treatment of
advanced additives that protects motors against wear,
rust and deposits. They excel in both high-horsepower
applications and all-day trolling conditions. |

Certified
AMSOIL Formula 4-Stroke®
Synthetic
Marine Oils are certified by the National
Marine Manufacturers Association (NMMA) for use
in four-stroke outboard motors. These high-quality oils
demonstrate outstanding performance, exceeding the NMMA
“FC-W” (Four Cycle-Water) specification requirements.
AMSOIL Formula 4-Stroke®
Marine Oils fulfill
the warranty requirements of four-stroke outboard motor
manufacturers. |

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.
While automobile engines normally operate at around 2,500 rpm,
outboard motors can run twice as fast, requiring greater
levels of wear protection and better bearing durability
than automobiles. To ensure good
protection, the NMMA set minimum shear stability
requirements for FC-W. AMSOIL Formula
4-Stroke® Synthetic
Marine Oils greatly exceed the FC-W shear
stability requirements, outperforming competitive oils to deliver a superior
lubricating film.
Four-stroke outboards feature vertically mounted
crankshafts, limiting oil retention at shutdown and
increasing the likelihood of dry starts and accelerated
wear. AMSOIL Formula 4-Stroke®
Marine Oils contain a high concentration of premium-quality anti-wear additives that provide an extra level
of wear control upon start-up (see Four-Ball Wear Test graph
below).

Exceeds Both the API and NMMA FC-W Requirements for Shear
Stability
In addition to be subjected to higher RPMs,
prolonged idling and low operating temperatures contribute to
fuel dilution, further thinning the oil. To ensure adequate
protection for their engines, marine engine manufacturers set
minimum high-temperature/high-shear (HTHS) viscosity limits.
AMSOIL Formula 4-Stroke® Synthetic Marine Oils
are shear stable and formulated with sophisticated oil additive
chemistry, exceeding the HTHS requirements of both the API and
NMMA FC-W (see High-Temp/High-Shear Test graph below). |

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. AMSOIL Formula 4-Stroke® Synthetic Marine
Oils are 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® Synthetic
Marine Oils are recommended for
gasoline fueled four-stroke outboard, inboard, inboard/outboard
(I/O) and personal watercraft motors.

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.
