Not Ranked
I have been using Royal Purple 20w/50w for two years now, I am having no problems, I change it once a year and my pressure runs 53psi at start up when its cold after hard running it drops to 45psi, my eng seems to run about 10deg cooler also.
I started using it after my eng break in about 3k miles I have 8K on it now.
Allot of your Marine guys use it, call your local boat dealer and see what they have to say about it.
