Customer Ratings & Reviews

I have been using HP marine oil since I bought my boat five years ago and I have never had a problem with it. I also have noticed less smoke than the product that I was using prior. ??

2015 nitro boat with mercury 200 2 stroke, less knocking noises with this oil compared to mercury oil

In my outboard premixed

Switched to amsoil HP marine last year, Really impressed makes my Mercury 200 EFI run much cleaner , considerably less smoking on start up,

I've been using this product for a few years now and so far it appears to doing its job with providing max protection for my Merc ProXS.

Great product have been using this product for 20 years on all my Recreational vehicles

Burns cleaner and my boat starts easier

The best oil on the market

I use it in my Bass Tracker fishing boat.

I have had 15 different outboard engines over the years. I started running this oil 3 years ago in a Johnson 75, 1981 model. The cheap oil kept fouling bugs every 90 days due to carbon build up. I switched to the factory synthetic hd50 and plugs lasted 6 months but still smoked a lot. Changed it to amsoil and smoke stopped and so did the carbon. Plugs were now changed at 1 year but didnt need it. Compression numbers stayed the same for three years. Now I have a merc 115 that I'm switching from their factory semi synthetic oil to amsoil.

I use this particular oil in my boat it runs more efficiently and the oil I use in my vehicle doesn't break down like any other oil I have used . You can definitely go by there intervals on changing it !

I liderally run amsoil in everything I own that has at motor. My mercury optimax has 1300 hours on it and I'm pretty convinced it's because of HP marine.

Beautiful product, no smoke i only use amsoil on all my different machine

I have been using this product for several years no issues low smoke low odor spark plugs last longer

The 2 stroke marine oil keeps our 1989 evinrude motor running smooth.

Use on a 2006 yamaha 225 HPDI motor from new Great product. Need more promo codes for shipping.

I was in need of two stroke oil for the start of my bass tournament season. After speaking with a buddy who is also a bass fisherman he is also a dealer of Amsoil Products. He convinced me to give it a try. I've burned through two and a half gallons of the HP Two Stroke oil and I couldn't be happier! The smoking has all but disappeared, my prop comes out of the water clean. I'm convinced it's the oil! I'm getting ready to order another case! Thanks Amsoil...

Been using this oil in my oil enjected Yamaha outboard for three years now. Very little smoke on start up and no visable smoke at idle or full throttle. As long as it performs this good I have no plans of changing oils.

I put this in my evinrude 175 made a total difference in the performance from an idle to wide open I could tell a difference

I use it in my Mercury outboard it runs smooth and clean.
