Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil



Specifically designed for outboard motors, Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil contains a heavy dose of low-temperature dispersant additives that excel at reducing varnish, carbon and deposit formation in water-cooled motors. Its low-smoke, low-odor, low-toxicity properties produce fewer emissions at 100:1 mix ratios than oils mixed at 50:1, benefitting operators and the environment. Outboard Synthetic 2-Stroke Oil is formulated to prevent "oil loading" and plug fouling for rapid throttle response, making it ideal for trolling motors.


AMSOIL Synthetic 2-Stroke Oil has been providing improved performance and protection in two-stroke engines since 1973. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job protecting your engine.

Engine Protection
Outboard Synthetic 2-Stroke Oil provides premium protection and performance at 100:1 mix ratios. It is formulated for hot-operating two-stroke outboard motors, effectively fighting carbon and deposit formation and preventing ring sticking.

Smokeless Operation
Outboard Synthetic 2-Stroke oil's synthetic formulation burns cleanly. When mixed at 100:1, smoke is virtually undetectable. Boaters subjected to smoke and fumes benefit from these low-emission properties.

  • Excellent lubricity and cleanliness properties
  • Controls friction and helps prevent wear, plug fouling, ring sticking and exhaust port blocking
  • Improves throttle response
  • Lowers or eliminates smoke
  • Delivers outstanding protection and performance at lean mix ratios
  • Anti-rust formulation counteracts the damp environments often encountered in outboard applications

APPLICATIONS
For pre-mix use in two-stroke outboard motors, personal watercraft and jet boats that specify TC-W3. For maximum performance, mix with gasoline at 100:1 regardless of the mix ratio specified for the equipment. Richer mix ratios may be used where desired.

    Describe the issue

    I'm running this oil at 100:1 in my 2004 Yamaha 40 on a 16' Flats skiff. Super clean burn with little smoke and quicker acceleration. This motor on this boat has seen many many hours in saltwater from the Carolinas to the Florida Keys, it just keeps running smooth as silk.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best 2 Stroke Oil Ever
    By  Jerry,  a  Verified Buyer  from  Michigan  on  June 17, 2021

    Describe the issue

    I've been using this stuff for several years and it is the absolute best 2 stroke oil on the market. New 2 stroke motors are no longer made so I need to do everything I can to take care of my existing motor and that begins with choosing the right oil. A 100:1 mix may sound scary but I assure you this is not a worry. This oil doesn't smoke, it's a very small amount required, and the bottle is marked clearly so you know exactly how much to use. I can't imagine using any other oil for my Johnson outboard.
    Bottom Line
    Yes, I would recommend this to a friend.
