AMSOIL Synthetic 2-Stroke Injector Oil reduces wear and maximizes engine life. Its high lubricity and reliable film strength help protect against piston scuffing and bearing wear.

The introduction of the world’s first synthetic motor oil to meet American Petroleum Institute service requirements in 1972 set all-new standards for motor oil quality. AMSOIL synthetic motor oil outperformed conventional petroleum motor oils on all counts. It was clear from the start that this innovative product would play a major role in engine performance and engine life.

As the technology used in today’s marine applications has evolved, AMSOIL has remained ahead of the curve in performance and protection with products formulated to deliver clean engine performance and control harmful deposits, wear and rust. AMSOIL synthetic lubricants are engineered to protect your watercraft in all conditions so you can remain carefree and on the water longer.

From fishing boats to personal watercrafts, the extensive gallery of products AMSOIL has to offer can help you keep your marine outboard protected and ready for hours of fun.

Pleasure Boats
From high-speed water sports to idle rides around the lake, pleasure boats offer limitless opportunities for fun. Regardless of your preference — high-rpm towing or low-speed cruising — engine protection is key to keeping the outing from turning from fun to aggravating. AMSOIL synthetic lubricants are engineered to reduce friction for outstanding protection and maximum performance on the water.

Personal Watercraft
Repeated throttle bursts and sustained high speeds put your personal watercraft to the test. AMSOIL synthetic lubricants are designed to provide excellent wear protection and maximum performance so you can ride harder and play longer.

Fishing Boats

A bad day of fishing beats a good day at work, but subpar engine performance or malfunction can ruin any day on the lake. AMSOIL synthetic marine lubricants are formulated to keep two- and four-stroke engines operating reliably at peak efficiency so your time on the water remains stress-free.

Pontoon Boats

An evening cruise or day-long excursion on the pontoon can offer the perfect way to wind down after a week’s work. AMSOIL marine lubricants are engineered with advanced synthetic technology to protect marine equipment, providing reliable performance and peace of mind on the water.

Sometimes finding the adequate oil for your Marine Outboard can be difficult, particularly if you’re just starting using one.
But AMSOIL’s here to help, search your model on our guide and find the best products to keep your Marine Outboard in the best conditions. 


You can be confident that using AMSOIL synthetic lubricants or practicing extended drain intervals does not void your new vehicle or equipment manufacturer’s warranty. In addition, all AMSOIL lubricants and filters are covered by the AMSOIL Limited Warranty.

I'll share my personal experience on being an AMSOIL dealer, and answer any questions you may have!
Most anglers, boaters and personal watercraft owners are as interested in protecting our waterways for future generations as they are in enjoying them now. HP Marine® Synthetic 2-Stroke Oil offers a unique combination of high performance and low aquatic toxicity. It has passed stringent tests developed by the Organisation for Economic Cooperation and Development to measure the effects of oil-contaminated water on common marine organisms.

Testing of HP Marine revealed a 100 percent survival rate of Daphnia Magna neonates (water fleas) and fathead minnows exposed to increasing concentrations of HP Marine mixed in water. In concentrations of less than 25 percent, algae (Pseudokirchneriella subcapitata) showed no reduction in growth or reproduction rates. These test results confirm that HP Marine is a smart and environmentally safe option for boaters and personal watercraft owners.

Outboard Synthetic 2-Stroke Oil Keeps 1974 Evinrude Running Str

So many variables determine the life expectancy of an outboard motor that it’s hard to predict with any accuracy how long an outboard motor will run.

But almost anyone would agree that a 1974 Evinrude that is still performing well in 2017 is unusual. If you’re the guy who got it for free, you’re thrilled.

Dealer Mark Neibuhr of Sequim, Wash. has a 1974 Evinrude Silver Starflite 135 hp outboard that he still uses. “I acquired this boat around ‘93 or ‘94, (totally stripped and gutted) and was given the outboard, which needed rebuilding,” Neibuhr said....(Read More)
