Product Applications
hp Injector is recommended for use in all two-cycle outboard motors including, but not limited to, Mercury ® EFI & Optimax ®, Johnson ® and Evinrude ® FICHT ® and E-TEC ™, Yamaha ® HPDI, Nissan ® and Tohatsu ® TLDI ®, Suzuki ®, Mariner ® and Force ®. Also recommended for use in all two-cycle personal watercraft and jet boats, as well as snowmobiles, motorcycles and ATVs.

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.

Product Description
hp Injector is a precise synthetic formulation that exceeds the lubrication demands of modern two-cycle motors. Today's two-cycle outboard motors operate at higher temperatures and at leaner oil and fuel ratios than older motors. This difficult operating environment requires proper lubrication technology to keep motors running long and strong. hp Injector is a premium lubricant engineered with AMSOIL synthetic base oils and MAXDOSE advanced additives. It contains up to 30 percent more additives than other TC-W3 two-cycle oils for "super clean" operation. And because AMSOIL synthetic oils are more durable, they are perfect for lean mixture operations. In addition, this AMSOIL exclusive product produces low smoke and odor and has low aquatic toxicity properties, making it ideal for boats.

hp Injector improves engine life. It helps prevent deposits that cause ring sticking and ring jacking (carbon build-up behind the ring, forcing it outward), a phenomenon that occurs in modern DFI outboard motors. hp Injector reduces wear. It has excellent lubricity properties and provides a good lubricating oil film, protecting pistons and bearings. hp Injector protects against rust, an important feature where motors are subjected to water. hp Injector provides superior performance in direct fuel injected (DFI), semi-direct fuel injected (SDI), electronic fuel injected (EFI) and carbureted outboard motors, as well as other recreational equipment.
