Engine Oil

AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil (PCO) provides the ultimate in diesel engine protection. Specifically formulated for long-life, it resists oxidation and thermal breakdown, retains viscosity and eliminates sludge and varnish formation. Outstanding lubricity provides unbeatable wear protection and maximum fuel efficiency. It contains special performance additives for acid and soot control. Extended drain capability reduces downtime and oil expenses.

AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD) has a fuel efficient formula for gasoline
and diesel engines. It contains the beefiest additive package of all AMSOIL motor oils and delivers better wear protection than other popular diesel oils, effectively reducing fuel consumption. These oils contain anti-rust agents that shield engine metals from water. They are formulated with 12 Total Base Number for dependable, long-lasting acid inhibition and corrosion protection needed in the operation of diesel marine engines. Generally, motor oils average 7 TBN, offering significantly lower corrosion protection than AMSOIL diesel oils.

Saber Outboard Synthetic 100:1 Pre-Mix 2-Cycle Oil

(ATO)contains lower temperature dispersants for water-cooled outboard motors. It is specifically designed for lean mix ratios in pre-mix applications. Extensive testing shows superior lubricity and cleanliness properties at lean mix ratios. DOMINATOR Synthetic 2-Cycle Racing Oil (TDR) is recommended for racing applications in outboard motors. AMSOIL DOMINATOR Synthetic 2-Cycle Racing Oil is specially engineered for unsurpassed protection of high performance two-cycle boat motors. It contains heavier synthetic base oils that provide more lubricity for “on the edge” operation. DOMINATOR reduces friction and protects pistons and bearings subjected to the rigors of racing. DOMINATOR contains an exact blend of proprietary additives for clean motor
operation.

HP Injector Synthetic 2-Cycle Oil

(HPI) is a precise synthetic formulation that provides superior performance in direct fuel injected (DFI), electronic fuel injected (EFI) and carbureted outboard motors, as well as other recreational two-cycle equipment. HP Injector exceeds the lubrication demands of modern two-cycle engines. It contains premium synthetic base oils and MAX-DOSE additive system.

INTERCEPTOR Synthetic 2-Cycle Oil

(AIT) is engineered specially for personal watercraft and jet boats. It excels in power sports applications and engines equipped with exhaust power valves. It contains the finest synthetic ester base oils and additives available
for exceptional cleanliness properties. INTERCEPTOR is the result of years of field testing, which provided some of the most severe conditions possible. INTERCEPTOR
excels at controlling exhaust valve sticking and provides outstanding overall lubrication properties.

Synthetic Water Resistant Grease

(GWR) is an extreme-pressure lithiumcomplex wheel bearing grease specially formulated for extreme resistance to water washout. It is the grease of choice for protection
of frequently wetted components, such as marine trailer wheel bearings. AMSOIL Water Resistant Grease forms a shield against rust and corrosion, protecting components during use and storage.

Fisherman Saves Time and Money

Commercial fisherman Paul Daniels switched his Detroit
Diesel 525 hp 12V-71T boat main engine over to AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil and an AMSOIL By-Pass Oil Filter to increase engine life and decrease maintenance. Daniels had been changing his conventional oil at 250- to 300-hour intervals. With AMSOIL products on board, he conservatively increased his change intervals until he reached his present 2000 hour oil changes with sampling and filter changes at 500 hours.

“We fish three to six days at a time, sometimes trawling
24 hours a day. The engine runs at continuous load most
of the time, which is ideal for a Detroit Diesel. But there’s
no getting around it—we really work that engine. “AMSOIL Heavy Duty Diesel and Marine Oil and the AMSOIL by-pass filter give me the outstanding protection I demand and the extended drain intervals I want. I appreciate the savings in time and money.”

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. V8-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?

With 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 synthetic motor oil and AMSOIL by-pass oil filter combination provides 400-hour oil change intervals and engine life up to 2500 hours — that’s 16 times greater oil service life and five times greater engine life — a huge savings for Shotover Jet Ltd.
