Updated for 2016. Find a substitute for marine oil products from over 70 brands.

AMSOIL Marine Group 2016
This cross-reference guide gives you an AMSOIL substitute for most two or four-cycle outboard/marine engine oils and lower unit gear oils sold in the United States and Canada. We have examined the products from over 70 oil brands and have listed a first-rate substitute that will dramatically improve the performance and extend the life of your boat or personal watercraft engine. Best of all, we can sell AMSOIL Synthetic Marine Oils at wholesale and ship it right to your door.

You will note that the vast majority of TC-W3 marine 2-stroke oils have two AMSOIL alternates listed, with those being AIO Synthetic 2-Stroke Injector Oil and HP Marine 2-Stroke Synthetic Oil. The reason being is that either of these products are a viable upgrade over most ordinary outboard two-cycle engine oils. AIO Injector is a versatile, value-priced synthetic, while HP Marine is AMSOIL’s best offering for 2-stroke marine applications. Either will perform exceptionally well, but you can decide if you want a great oil (AIO Injector) or our absolute best (HP Marine).  If you have questions, feel free to contact us with the form on your right or call us at 1-800-748-5781.

Here is a description of our AMSOIL substitutes.

HP Marine Synthetic 2-Cycle Oil– AMSOIL’s best for 2-cycle marine engines requiring the TC-W3 specification. Test-proven for the demanding requirements of Evinrude E-TEC engines. Also ideal for direct fuel injection (DFI) 2-cycle engines (DFI). Low-smoke, great performance and low aquatic toxicity rounds out an unbeatable package. Suitable for oil injection or 50: premix.

“AIO” Injector Synthetic 2-Cycle Oil – A multi-purpose synthetic 2-cycle oil that is value-priced. Can be used for outboards requiring the TC-W3 spec or personal watercraft requiring the API-TC spec. It can also be used in your snowmobile in the winter. But don’t let AIO Injector’s versatility or price fool you. This product is a serious synthetic challenger that fights wear and performs like a champ. AIO Injector is suitable for direct fuel injection (DFI) engines. Can be used in oil injected engines or premix at 50:1.

Saber Outboard Synthetic 2-Cycle Pre-Mix Oil – A dedicated outboard pre-mix oil for outboards that covers any mix ratio. Upgrade the performance of your outboard engine with dramatically reduced smoke and odor, improved throttle response and exceptional wear control.

Interceptor Synthetic 2-Cycle Oil– This is the ultimate engine oil for 2-stroke personal watercraft engines that require the API-TC specification. Many personal watercraft such some Sea-Doo models and 2-stroke Yamaha WaveRunners require a low-ash engine oil rather than a TC-W3 oil for water-cooled outboards. AMSOIL Interceptor provides supreme performance along with clean exhaust power valves.

AMSOIL 10W-30 4-Stroke Marine Synthetic Motor Oil– An NMMA FC-W “Catalyst Compatible” approved engine oil for 4-stroke outboard, inboard and personal watercraft engines. Provides synthetic wear control and outstanding anti-rust protection in marine engines suggesting a 5W-30, SAE 30 or 10W-30 marine engine oil.

AMSOIL 10W-40 4-Stroke Marine Synthetic Motor Oil– A synthetic oil for gasoline-powered 4-stroke outboard, inboard and personal watercraft engines. An NMMA FC-W “Catalyst Compatible” licensed motor oil. Ideal for marine engines requiring an SAE 40, 15W-40, 25W-40 or 10W-40 oil.

AMSOIL 25W-40 Synthetic-Blend Marine Motor Oil– Formulated to comply with Mercury and Mercruiser warranties. Suitable for outboard, inboard and stern drive motors. NMMA FC-W “Catalyst Compatible” licensed.

AMSOIL 15W-40 Synthetic Heavy Duty Diesel & Marine Motor Oil– A robust motor oil formula for heavy-duty diesel marine engines. Provides long service life and long engine life in severe service conditions of marine diesel engines.

AMSOIL Universal 75/80W-90 Synthetic Marine Gear Lube– This lower unit marine gear oil is ideal for any application requiring a 75W-90, 80W-90 or SAE 90 gear oil. Great for outboard lower units, stern drives, v-dries and ZF Marine Transmissions. The high-tech synthetic formula reduces heat and friction, even with 10% water contamination.
