I thought it would be a good idea to put interceptor in my 2008 optimax 150 to cut down on the smell from the mercury oil. I figured that since it was a mid grade oil that it would be fine. However, when I was putting the box on the shelf, it says that it's not recommended for outboards and that hp injector is. I can't seem to find oil specs to find out if this is okay.
Does anyone know if this is acceptable? My motor is still under warranty and I don't want to void it.
