Product Highlights View Full Description

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

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.

Best outboard 2 stroke oil for everyday use!

By 

from Deland, Fl.

Verified Buyer

Comments about HP Marine Synthetic 2-Stroke Oil:

I use both my boats year round here in Florida and have had zero problems with lubrication or carbon buildup since I started using HP Marine back in 2011. I have many friends that I have convinced to try Amsoil and they have noticed easier starting, increased power, and reduced carbon buildup on pistons. We just love the results from this great Oil! Very little smoke and a pleasant smell make this my go to oil for my outboards. I will use nothing else. You should too!

Great 2 stroke outboard oil.

By 

from undisclosed

Verified Buyer

Comments about HP Marine Synthetic 2-Stroke Oil:

I run this in my 09 250 Yamaha HPDI bass boat. Could not be happier, clean plugs, engine runs flawless, very little smoke, and costs less than Yamalube. I also run in my old 25 hp Mercury tiller steer, runs and trolls at idle speeds great. Formerly ran this oil in my 150 hp Johnson for almost 10 years and had zero issues with the motor and a friend now owns the boat and still running great using same oil. 5 stars and costs same if not less than comparable synthetics.

Amsoil Does It Again

By 

from Boise, Idaho

Verified Buyer

Comments about HP Marine Synthetic 2-Stroke Oil:

After having used Merc*** Quick****** in my two stroke outboards for many years, I decided to try Amsoil HP two stroke marine oil. One of the first things I noticed while trying this oil was that the smoke from the oil was greatly diminished.

I also noticed that the outboard seemed to run smoothly with less vibration at idle.

I wish I had tried this oil many years ago and I will use this oil for many years to come.

Comments about HP Marine Synthetic 2-Stroke Oil:

I have a 2007 Yamaha VMAX 150 HP on my saltwater flats boat. I was using the Yamaha Lube, but the Amsoil product is superior. I have less smoking, and less consumption with the he Amsoil. It is noticeable. I have now used this product for a year, so it isn't a new phenomenon.
