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. ??

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.

I use Amsoil in all my motorized vehicles

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.
