HP Marine Synthetic 2-Stroke Oil



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 amsoil.com/proof.

    Run oil in my powered parachute
    By  CHARLES,  a  Verified Buyer  from  Summitville In  on  April 04, 2021

    Describe the issue

    I have run this cycle oil in my powered parachute with a Rotax 582 for almost 9 years. The people I fly powered parachutes with convinced me to run Amsoil when I first started flying. Had a local store that we bought from that went out of business. Couldn’t find anyone else. So I became a preferred buyer. Also I have seen Rotax engines disassembled with several hundred hours on them that use Amsoil and was impressed how clean they were with minimal wear. I now run Amsoil oil exclusively in my machine.
    Bottom Line
    Yes, I would recommend this to a friend.
