hp Injector is a precise synthetic formulation that exceeds the lubrication
demands of modern two-cycle motors. Today’s two-cycle outboard motors operate at higher
temperatures and at leaner oil and fuel ratios than older motors. This difficult operating
environment requires proper lubrication technology to keep motors running long and strong. hp
Injector is a premium lubricant engineered with AMSOIL synthetic base oils and MAXDOSE advanced
additives. It contains up to 30 percent more additives than other TC-W3 two-cycle oils for “super
clean” operation. And because AMSOIL synthetic oils are more durable, they are perfect for lean
mixture operations. In addition, this AMSOIL exclusive product produces low smoke and odor and has
low aquatic toxicity properties, making it ideal for boats.
hp Injector improves engine life. It helps prevent deposits that cause ring
sticking and ring jacking (carbon build-up behind the ring, forcing it outward), a phenomenon that
occurs in modern DFI outboard motors. hp Injector reduces wear. It has excellent lubricity
properties and provides a good lubricating oil film, protecting pistons and bearings. hp Injector
protects against rust, an important feature where motors are subjected to water. hp Injector
provides superior performance in direct fuel injected (DFI), semi-direct fuel injected (SDI),
electronic fuel injected (EFI) and carbureted outboard motors, as well as other recreational
equipment.
Applications (2-Cycle Recommendations Chart)
hp Injector is recommended for use in all two-cycle outboard motors including, but not limited to,
Mercury® EFI & Optimax®, Johnson® and Evinrude® FICHT® and E-TEC™, Yamaha® HPDI,
Nissan® and Tohatsu® TLDI®, Suzuki®, Mariner® and Force®. Also recommended for use in all
two-cycle personal watercraft and jet boats, as well as snowmobiles, motorcycles and
ATVs.

Q: A boat owner asks, Can I use Amsoil HP in an
Evinrude e-tech outboard? A: Yes you can i
replied. Read our Marine E-TEC Field Study below. Our Synthetic 2-Stroke marine Oil provides
excellent protection in Evinrude engines programmed to the lean-mix setting.
Overview Evinrude® E-TEC™ marine engines are unique in that they offer an
alternative, lean-mix setting that allows the engine to use less oil. Whether programmed to operate
at the standard mix ratio or reprogrammed to the lean-mix setting, these engines use sophisticated
electronic equipment to monitor conditions, including rpm and throttle position, to determine the
appropriate gas-to-oil mixture. To use the lean-mix setting, however, customers must have their
engines reprogrammed by an Evinrude dealer and agree to use Evinrude XD100™ oil exclusively, often
at a higher cost compared to other oils. Bombardier Recreational Products (BRP®), the manufacturer
of Evinrude engines, has not established a performance specification against which to qualify other
oils.
Objective
Determine through real-world field validation if AMSOIL HP MarineTM Synthetic 2-Stroke Oil meets
the
increased performance needs of reprogrammed Evinrude E-TEC engines operating on the lean-mix
setting. Further determine if consumers can safely use HP Marine Synthetic 2-Stroke Oil in E-TEC
applications in place of Evinrude XD100 2-Cycle Oil.

Methodology In conducting this field study, AMSOIL partnered with SEA-TOW®,
a marine rescue organization specializing in non-emergency calls for assistance. Based in Naples,
Fla., SEA-TOW typically tows large marine vessels, including yachts and sport cruisers. The engines
that power their towing vessels routinely encounter heavyduty, high-stress operation and provide
the ideal environment for testing motor oils. Both Evinrude 250 hp E-TEC engines used in the study
were initially operated on the standard oil injection setting for 28 hours. An Evinrude dealer then
reprogrammed both engines to operate on the lean-mix setting for the duration of the study. The
starboard engine’s oil reservoir was filled with AMSOIL HP Marine Synthetic 2-Stroke Oil, the
portside engine’s oil reservoir with Evinrude XD100 2-Cycle Oil. The validation period lasted a
total of 534 hours; approximately 240 hours were spent under severe-service conditions when the
SEA-TOW boat towed marine vessels. The engines were closely monitored for the duration, and upon
completion, both were disassembled and rated by a calibrated ASTM rater who evaluated each engine
based on NMMA TC-W3 criteria for two-cycle marine engines. Merit ratings for each set of components
(e.g. piston skirts, piston rings, etc.) were determined using the appropriate techniques and
rating scales as defined in the Coordinating Research Council, Inc. Deposit Rating Manual No. 20.
The evaluation included an examination of the condition of all engine parts. Some components
received a merit rating based on a 1-10 scale, with 10 representing a component free of defects and
0 representing catastrophic distress. Others received merit ratings indicating the percentage of an
area with defects (e.g. the percentage piston skirt area containing scuffing). The average merit
rating of each group of components is shown in this study.

Piston Scuffing 0.00%
|
The pistons in both engines received nearly identical high merit ratings for varnish, indicating
both oils
excelled at inhibiting varnish formation. Scratching refers to the alteration of the skirt surface
in the form of sharp linear depressions from lapping of mating surfaces by fine particles suspended
in the lubricant, fuel, air or imbedded in a surface, while scuffing appears as a matte finish. The
presence of scuffing is commonly lubricant-related. In both engines, scratching was present at
trace to very light levels, represented by the low percentage ratings. Both oils completely
prevented piston skirt scuffing, earning perfect ratings of 0.00 percent scuffing.

While undercrown deposits do not impede performance, heavy piston crown deposits can cause
preignition and consequent poor performance. Two-cycle oils must resist heavy deposit formation on
the piston crown caused by the high temperatures inside the combustion chamber. HP Marine
demonstrated strong performance in the area of piston crown deposits.

Carbon deposit buildup in the exhaust ports restricts air flow and can cause reduced
power and poor overall performance. Both engines displayed virtually no exhaust port blocking,
represented by the low percentages. Deposits were likewise minimal, with ratings near perfect
10s. In the area of cylinder bore scuffing, both oils limited metal-to-metal contact and
achieved perfect scores of 0.00 percent. The cross-hatch pattern remains visible on the cylinder
walls of both engines.

The main bearings experience intense pressure and represent a common area
where metal-to-metal contact can occur. Both oils limited wear to trace to light levels and the
bearings were found to be in “good” condition according to the calibrated ASTM rater. Both oils
nearly eliminated deposits as well.
Conclusion
As demonstrated in real-world,
severe-service testing, AMSOIL HP MarineTM Synthetic 2-Stroke Oil meets the stringent
performance needs of Evinrude® E-TECTM marine engines programmed for reduced oil consumption.
Operated simultaneously with an engine lubricated with Evinrude XD100, an identical engine
lubricated with HP Marine demonstrated strong performance and excelled in critical-component
lubrication. The cylinder bores, for example, demonstrated 0.00 percent scuffing, while the main
bearings demonstrated only trace to light wear. The engine also displayed no ring deposits,
earning perfect merit ratings. Finally, HP Marine effectively limited deposits throughout the
engine and met the increased performance demands required by the lean-mix setting. Results prove
the effectiveness of AMSOIL HP Marine Synthetic 2-Stroke Oil in Evinrude E-TEC
applications. AMSOIL fully supports the use of HP Marine
as a replacement for Evinrude XD100 in Evinrude
E-TEC engines, and warrants its use according to the AMSOIL Limited Liability Warranty
(G1363).
