Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil (ATO)

Amsoil Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil (ATO)

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.
