I have run this cycle oil in my powered parachute with a Rotax 582 for almost 9 years. The people I fly powered parachutes with convinced me to run Amsoil when I first started flying. Had a local store that we bought from that went out of business. Couldn’t find anyone else. So I became a preferred buyer. Also I have seen Rotax engines disassembled with several hundred hours on them that use Amsoil and was impressed how clean they were with minimal wear. I now run Amsoil oil exclusively in my machine.
Switched to Amsoil HP Marine three years ago, I was very reluctant to switch from a Mercury oil , so glad I did , burns clean, little smoke, runs great!!
I Deleted my oiler then I started to have problems with Fowling plugs at idle or low rpms due excess oil so I changed my oil up to amsoil and I haven’t Fowled plugs since
i use this in an 1988 Johnston 40hp outboard that has been mine since new. Always used Amsoil product. Low exhaust smoke and sheen. Mixes well and stays that way. Worth the few pennies more to have a reliable engine.
Bought the 1 gallon great price also noticed smokes a little less when running
Bottom Line
Yes, I would recommend this to a friend.

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.
