Just came back from a 10 day fishing trip. Used the AMSOIL in the boat for the first time. Motor ran great, seemed to run smoother with this oil.

I love this two cycle oil. I believe its brought my engine back to its like new running condition.

Exelent product

Been using this oil in my mercury 200 EFI for three years , burns cleaner really happy with the way it makes my old mercury run

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.
