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

Twin Yamaha HPDI 300's Great product Doesn't smell doesn't smoke and the engines run smooth and no fouling of the plugs even after a long day of trolling speed.

La.meilleur huile a injection direct et consome moin d huile qu avec la xd 100

Works great!

I’ve used AMSOIL products since 2008 and have never been disappointed with their performance as prescribed…..IT WORKS!

Its a great oil i run it in my mercury sport jet 200

I switched to Amsoil HP Marine and my engine is running great and I see a lot less smoke. I just wish that preferred customers got better shipping options like Amazon does. I don't always need 100 dollars worth of oil laying around just to get free shipping.

Does not smoke as bad as some oils little on the high side price wise but hopefully better than other oils

Thanks

Been using this in my 250 HPDI outboard since it had 90 hrs on it. It now has 1200 trouble free hours. Low to no smoke and just great all around!

Great product. Marine engine runs very well with this oil and from what I’ve seen keeps the wear to a minimum

Always pleased to order through Amsoil for my marine oil. Solid experience all around.
