Keeps my outboards running fine . Very good lubricant.

Great product. Works perfect.

I have been using this product for 30 years No other oil compares , I will never change.

This stuff works great in my 60hp Yamaha Outboard, does a great job and is reasonably priced I always keep a extra quart handy at all times.

Works great no exhaust goo

Performs awesome and a lot less smoke when trolling on our older outboard

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.

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.

I have never had a problem with this product

I have used the 50 to 1 for years and was excited to see the 100 to 1. My 2000 xployer 400 has used the same plug now for 3 years. My boat motor starts much easier and it burn very clean.

Best quality oil I’ve ever used. My last leaf blower lasted 22 years while using this oil!

This can also be used like AMSOIL's Upper Cylinder Lubricant for passenger-car applications! It will not harm any catalytic converters since it burns off ashless with the TC-W3 spec. Add about 1 oz for every 4-5 gallons (up to 500:1 is ok). HP Marine 2 Stroke works as well but I prefer the Outboard oil as the 100:1 premix makes the additives much more robust with this than with HP Marine's 50:1 mix ratio. There is extensive Internet documentation, including forums and YouTube videos, on using TC-W3 2-stroke oil as a fuel additive.

good stuff is not cheap/cheap stuff is not good/amsoil good stuff

This is the best two stroke oil you can get. No smoke at all and I have never fouled a plug. I have a 1988 mercury outboard that still runs perfect and never rebuilt at 100/1 mix

Started 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.

I 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.

The 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.

This oil works great! Smoke from the engines reduced

I 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.
