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.

    Confusing options - use the right product in outboards
    By  ANDREW,  a  Verified Buyer  from  VASHON  on  September 29, 2021

    Describe the issue

    I have used the Amsoil Marine Synthetic in my 225 Yamaha Injection 2 stroke outboard for while. I purchased the 2 stroke Amsoil "injection" oil thinking this was the correct stuff. It stated that it was for outboards and snowmobiles. When this was injected it made the engine run rough, and the power diminished unless the motor was at high speed. Luckily got home from many miles away and called Amsoil. Instructed to use the Marine Outboard product. Once cleared of the wrong Amsoil "Cheaper and less effective" oil the outboard returned to normal and is running fine. I told the folks at Amsoil that they needed to remove "outboard" from the description in the other "injection" oil to avoid confusion. There is a difference in price on the very expensive Amsoil products, but you need to get the correct product.
    Bottom Line
    Yes, I would recommend this to a friend.
