This has been the best two cycle oil I have used in my outboard motor

I’ve been using this oil for 17 years. My Opti’s have 1300 hour on them and compression is still great. Had to run home on one motor due to a sensor issue and the single engine under hard running conditions held up great. Tested compression after getting back and still perfect. Price is better than Opti oil too!

Well packaged! Very fast delivery! To soon to tell about the performance.

I have a 115 Mercery outboard on my 1998 pontoon.less smoke runs great

Used this stuff in my 91 kawasaki 550sx reed motor and it ran so much smoother then the kawasaki oil. Less smoke too. 40:1

I've been using HP 2 stroke oil through 3- 2 stroke outboards. Merc.200 Black Max, 70hp Yamaha, 9.9 Merc. Never replaced plugs mid season always ran great. Very little smoke even when trolling for hours on end. Great oil.

I am a strong supporter of Amsoil anywhere I use oil or fuel treatment it’s Amsoil

This is by far the best oil I have ever used. My 1996 Johnson FastStrike runs the best when I run HP Marine 2 Stroke.

Excellent product, less smoke,crisper throttle response.

I have used this oil for many years Never a fouled plug or excessive smoke. I only purchase this oil for my Outlaw Eagle 200 HP Merc.

As a tournament bass angler I depend on my equipment to perform at its best, Using Amsoil HP marine 2- stroke oil I know its a product I can depend on.

Less smoke,better warmup, engine smooth running,just all around better Oil than other brands. Look UT Vols playing Perdue in bowl game don't have much time to write more or would. Buy it won't regret GO VOLS

I love this oil. My Mercury 115hp 2 stroke outboard runs exclusively on this oil. I haven't missed a beat with combo 2 stroke oil and Ams oil gear lube

I have used the Amsoil Marine Synthetic in my 225 Yamaha Injection 2 stroke outboard for while. I purchased the 2 stroke Amsoil "injection" oil thinking this was the correct stuff. It stated that it was for outboards and snowmobiles. When this was injected it made the engine run rough, and the power diminished unless the motor was at high speed. Luckily got home from many miles away and called Amsoil. Instructed to use the Marine Outboard product. Once cleared of the wrong Amsoil "Cheaper and less effective" oil the outboard returned to normal and is running fine. I told the folks at Amsoil that they needed to remove "outboard" from the description in the other "injection" oil to avoid confusion. There is a difference in price on the very expensive Amsoil products, but you need to get the correct product.

Love this stuff use it on both my ski really cuts back in the smoke and they run so much smoother

Don’t bother with other oils, this specific Hpdi oil from Amsoil is #1. More hours out of your spark plugs and a more clean burn. My 2000 runs like a 2021

Since moving to this product the motor is running smoother and we are getting better performance.

I use HP Marine synthetic to replace XD 100

Been running hp marine 2 cycle oil in my Rotax 582 powered parachute for nine years. Had engine gone thru about 3 years ago. No appreciable wear was noted all that was needed was seals and gaskets.

Its a game changer for 2 strokes
