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.
- Excellent for Evinrude E-TEC factory-lean setting (replaces Evinrude XD100 2-Cycle Oil)
- Helps prevent deposits
- Protects against wear
- Low smoke
- Protects against rust
- Low aquatic toxicity
- Superior performance as an injection oil or at 50:1 pre-mix
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
