Outboard 100:1 Pre-Mix

Product Highlights

Designed for pre-mix applications as lean as 100:1 ratios or richer. Improves throttle response and lowers or eliminates smoke. Minimizes deposit formation and lowers emissions. Performance emphasis on the cooler operations of water-cooled motors.

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.

  1. I have a 1974 Fairmont Motocar with a 1 cyl 2 cycle engine. Manufacturers recommendation was 16:1 30w engine oil mixed with the gas. RPM in the range of 800-1900 max. What oil do you recommend and what ratio? And why for each please?
    Thanks

    1. Thank you for taking the time to contact AMSOIL with your question.

      For this two cycle engine, you may want to consider using our Dominator Two Cycle Race Oil (product code TDR). You could start with a mix ratio as rich as 32:1, and lean out to 50:1, and find a ratio that would be the best to use. A good ratio will allow the engine to run without smoking, and the spark plug color should be brown in color. If the spark plug looks wet, or you see smoke, you can continue to lean out the ratio.
