High-quality motor oil is critical for maximum performance in modern two-stroke marine motors. Direct fuel injection (DFI) improves combustion efficiency, delivering the extra power enthusiasts want, while leaner gas-to-oil ratios provide the reduced exhaust emissions the government mandates. The leaner ratio leaves less oil to lubricate and protect these hotter, more powerful motors, which invites deposits and wear that threaten engine performance and life. HP Marine is proven to excel in these harsh conditions. It controls performance-robbing friction, heat and wear, yet produces low smoke and has low aquatic toxicity properties. It's an oil as advanced as the engines it protects.
Outstanding Wear Protection
The elevated heat and friction of modern two-stroke marine motors can
exceed the film strength of inferior oils, increasing the likelihood
of scuffing and wear. HP Marine's exclusive synthetic formulation
provides increased lubricity for reduced wear during normal and
lean-mix operation (see field study results). In 534 hours of field
testing, HP Marine completely prevented piston skirt and cylinder bore
scuffing, demonstrating its superior lubricity and ability to reduce
friction between moving parts. It maintains a strong lubricating film
even in lean-mix, severe-service conditions, helping marine engines
achieve maximum life.
Excellent Deposit Control
HP Marine is formulated with MAXDOSE™,
a system of advanced additives for "super-clean" operation. It helps
prevent deposits that lead to poor performance. In field testing, HP
Marine inhibited ring deposits that can cause ring sticking and ring
jacking (carbon buildup behind the ring, forcing it outward), a
phenomenon that occurs in modern DFI outboard motors. It also
virtually eliminated exhaust port deposits for reliable, efficient
operation.
Proven in Marine E-TEC Field Study
HP Marine was installed in a 250-hp Evinrude E-TEC engine powering a
heavy-duty marine rescue vessel. Following a 28-hour break-in period at
the normal oil setting, the engine was programmed to its factory-lean
setting and operated for 506 hours prior to disassembly. An ASTM
calibrated rater examined and awarded each component either a merit
rating on a scale of 0 to 10 (with 10 representing no distress) or a
percentage rating (with 0 percent representing no distress). Results
prove HP Marine provided exceptional wear protection and deposit
control. For complete study results, visit amsoil.com/proof.
APPLICATIONS
Use in two-stroke marine applications that specify TC-W3, including
those made by: Johnson/Evinrude*, FICHT*, E-TEC*, Mercury* EFI ;
Optimax*, Yamaha*, Nissan*, Tohatsu* TLDI*, Suzuki*, Mariner*, Force*.
Use as injection oil or 50:1 premix (2.6 oz. per U.S. gallon of gas).
Compatible with mineral and synthetic TC-W3-type two-stroke oils; however, mixing two-stroke oils should be minimized.
