Product code : ATOBC-EA
Performance-Engineered for Outboards
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.

Great stuffStarted using Amsoil 100:1 outboard oil two years ago. It considerably reduced the smoke and idle load up on my 1990 Johnson GT150. Now she purrs like a kitten on idle and roars to life under power! Love this stuff. Highly recommend.Bottom LineYes, I would recommend this to a friend.

i have been buying this product for over 20 yearsBy  Rick The Wrench,  a  Verified Buyer  from  cohasset,mn  on  October 25, 2018I have been repairing outboards for over 35 years and the outboards that this product shines at are the OMC'S Johnson and Evinrude,s they have a vro system that fail and burn up powerheads I have converted them to premix 100 to 1 before and after burn downs and have great reviews as to them running better than they did new. They start better idle better and all around run better with less smok.Bottom LineYes, I would recommend this to a friend.

Great ProductThe oiler for my outboard has been removed and I premix the gas and oil. I have been running the 100 to 1 AMSOIL at a100 to 1 ratio for 6 years or more. I push the little 60 hard and have had no oil related problems. There is virtually no smoke and I have never fouled a plug. This is a great product. I think it has extended the life of the engine because the mechanics I consult tell me most of these motor are done in when the oiler fails. Its a great product that I will continue to use.Bottom LineYes, I would recommend this to a friend.

Worked good. 2 stroke boat engines smoked lessI used this on 2 boats both being 2 strokes. 1 is a bass boat with a 150 merc. Other is a offshore boat with twin 175 mercs. In both cases I started with 80:1 mix being new to Ams-oil. After intensive research I went for the 100:1 mix. Both boats smoke much less. They dont load up like before idling and trolling. Did a compression check on all 3 motors and all stayed the same. I will continue using this.Bottom LineYes, I would recommend this to a friend.

So far so goodI purchased this to use in my 1993 Johnson 150. Trying to cut down on smoke. It has helped some. I can say the idle seems much better and the obvious use of oil is cut in half.Bottom LineYes, I would recommend this to a friend.
