High-quality motor oil is critical for maximum performance in modern two-cycle 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 challenges. 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-cycle 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.
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 dis-assembly. 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. See “Field Study” above.

Applications
HP Marine™ is recommended for use in all two-cycle outboard motors including, but not limited to, Johnson® and Evinrude® FICHT® & E-TEC™ (replaces XD100™ 2-Cycle Oil); Mercury® EFI & Optimax®; Yamaha®; Nissan® and Tohatsu® TLDI®; Suzuki®; Mariner® and Force®.
It is also recommended for use in all two-cycle personal watercraft (PWC). Use as injection oil or as 50:1 pre-mix (2.6 oz. per U.S. gallon of gas) where NMMA TC-W3 or API TC oils are specified. Compatible with mineral and synthetic TC-W3-type two-cycle oils; however, mixing two-cycle oils should be minimized.
