Great oil. Run it in my Mercury Optimax Pro XS 250 for several years with zero issues.

…..really???

I was told about this oil by a friend that has racing outboard's and built them and I thought he was joking about it!! I tried it out a couple of year's ago and he was absolutely correct and have been using it ever since and will continue to use it!!

Great service. Fine product.

Love the stuff. 20-year-old 2 stroke engines barely smoke. Engines run clean and quiet and smell free.

10 years of service on my 1999 (rebuilt powerhead, 2012) and no mechanical failures...even at 100:1... enough said

Just a great product. No smoke, clean plugs, 2018 Evinrude Etec 250 runs like a champ! As it should!

I have used HP marine oil for many years in my finicky Johnson 115hp. Last year I tried a different oil and had many problems. After 600.00 in” diagnosis , they said it probably needed a new computer. I took it to a local small engine/ mechanic ( who is a true mechanic) it was the oil. Now a Hp marine oil for life

Been using HP Marine for many many years. Couldn't ask for a better value. Burns clean, protects well and is very affordable.

I like the peace of mind that comes with Amzoil protection. I run this product in my lean burn Mercury Optimax and feel confident there will be no lubrication and wear issues on this engine. I have used Amzoil products through the years in my air/oil cooled BMW motorcycles with great results. Amzoil is the only product in the motorcycles that doesn't cook off, even in the Texas heat.

Only oil I have used for 20 plus years

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.
