The E-TEC ultra performing HP Marine Synthetic 2-stroke Injector Oil

Another AMSOIL product which stands way ahead of the competition in performance. People in general don’t choose an oil because it adds to the overall performance but as a side benefit it’s built in.

Excellent for Evinrude® E-TEC™ factory-lean setting (replaces costly 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 Performance 2-Cycle Injector Oil for Outboard Marine

Buy & Pricing

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.

Gallons are the most popular size.

Outstanding Wear Protection over OEM Injector Oils

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 2-Cycle Injector Oil 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 over all other 2-Cycle Marine Injector Oils

HP Marine 2-cycle injector oil 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 build-up 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 – Archived

High Performance Synthetic Marine 2-Stroke Oil 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 Proof of superiority.

Other Materials on the AMSOIL HP Marine Injector Oil’s Performance

Complete E-TEC Marine Study on PDF. No reason to buy over priced OEM 2-cycle oil. AMSOIL offers superior protection as proven, better performance as reported from users and their own bulletproof guarantee against damage. (See warranty link and section below)
Overview to the above link: Evinrude® E-TEC™ marine engines are unique in that they offer an alternative, lean-mix setting that allows the engine to use less oil. Whether programmed to operate at the standard mix ratio or reprogrammed to the lean-mix setting, E-TEC engines use sophisticated electronic equipment to monitor conditions, including rpm and throttle position, to determine the appropriate gas-to-oil mixture. To use the lean-mix setting, however, customers must have their engines reprogrammed by an Evinrude dealer and agree to use Evinrude XD100™ oil exclusively (Often at a higher cost compared to other oils.) Bombardier Recreational Products (BRP®), the manufacturer of Evinrude E-TEC engines, has not established a performance specification against which to qualify other oils.

Basically, it’s always been the desire of the staff at AMSOIL to never put out a product which could be considered 2nd best. They consistently work with suppliers using the latest trends and technology to improve the state of the art in the industry.  There are no stockholders to hamper the quality of the final product. Price never makes a determination to the additives or direction used. They also constantly reverse engineer OEM products to see what they’ve been up (or haven’t) to and can assure the quality is not comparable. As a dealer attending the training events, some staff members report how far behind or even how they don’t even meet their own specifications. Of course, the proof is in the performance and the AMSOIL HP Injector oil is one of those we get a LOT of in store applause.

I especially remark on this product for the marine market because more so than in the automobile realm customers are pressured into using the OEM branded product. I have read in forums more times than any that boat owners are told that the OEM product such as the XD100 2-cycle oil must be used in order to protect the engine under warranty and to ensure any life thereafter. By making this demand the manufacturer is bound by law to provide that product at no charge. Yes! That is a fact and often companies have to re-issue owner’s manuals to correct the wording.

HP Injector Oil 2-stroke Applications

Use in two-stroke marine applications that specify TC-W3, including those made by Johnson/Evinrude, FICHT, E-TEC (replaces run of the mill XD100™ 2-Cycle Oil), Mercury EFI & Optimax, Yamaha, Nissan, Tohatsu TLDI,
Suzuki, Mariner, Force.* Use as injection oil or 50:1 premix (2.6 oz. per U.S. gallon of gas).

Compatible with mineral and synthetic TC-W3-type two-stroke oils; however, mixing two-stroke oils should be minimized.
