Customer Ratings & Reviews

I firmly believe there are no better oil / lubrication products on the planet than Amsoil. I don’t trust any other brand for my oil needs including my vehicles, boat, atv’s, and side by sides.

Replaced another brand with Amsoil HP Marine- same 50:1 premix but less smoke and runs smoother at idle. Only regret was not switching sooner!

Switched to this after reading reviews how much better it performs I totally agree. My motor doesn't smoke at all and no prop oil residue constantly.

I have only been using this oil for a year now but it's fully synthetic and a reasonable price

Great product all my river boat buddies run this oil and Love it 👍🤝

I’ve been using HP Marine on my own rig, and my customers like it too. The big thing is reduction in smoke from 2 cycle premix outboards. It pretty much sells itself for my two cycle outboard customers.

Used this in my 2 stroke Evinrude motor it smoked way less than regular oil. Highly recommend it.

Excellent oil if you have a 2-stoke outboad. Low smoke, non-fowling. Hard to find marine 2-stoke synthetic oil anymore.

Running in my 150 Etec for the past 80 hours with no issues!

Solid product that is dependable, especially in salt water. Very satisfied with the quality.

No other oil will go in my Yamaha 250 outboard or my ford F-350.

Changed to this oil from Optimax oil. A huge difference in performance , easier start up and cleaner burning. Love this oil !! Kevin

Use this in both of my mercury outboards, neither has any issues. Both are oil injected

I’ve been running this oil now for about 4 yrs or better. I’ve never seen anything like this oil before better performance hardly no smoke at all yeah really I’ve maybe seen it puff a very small amount out a couple of times. I’ve never had a skip , a fouled plug or a clogged injector no matter the fuel I use ,ethanol free or 10% ethanol added. Knock on wood they say guy if you never used this oil and wanting to try better results for your 2 stroke engine this is the one you need , it’s the best out there.

I've trusted amsoil since the 70's and I trust them now.

Great product, great delivery timing.

Great oil, motors with 1350 hours have perfect compression and plugs last a long time without fouling. Used this oil since engines were new.

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

Each year, before I use my boat, it comes out in the driveway and gets started using "earmuffs" for cooling. My engine is in new condition, even though it's a 1998! It's an Evinrude V4 115hp. It's always been on the cold blooded side and the first run of the year can be a challenge sometimes getting it to start and keep running! When I changed over to Amsoil, I poured all the Evinrude oil back into the container it came in, sloshed a bit of gas around to rinse it out, and reinstalled. After I filled the tank with Amsoil, I pumped the oil through the line to the mix point and started the motor. It still had a lot of leftover oil in it from the winter so it proved to be a stubborn start with the usual rough running. Then, when the Amsoil hit the mix, the motor smoothed right out! This year, it was much easier to start and a lot less smoke! Definitely makes a difference!

…..really???
