I don't subscribe to weird ratio oils its a smoke show as the amount that can be acceptable in a high ratio may be as simple as the oil has a higher viscosity ( thicker ) and has less thinning in the add pack.
If your asking if I like some of these "Magic Elixers Snake Oils" the answer is NO , I tear down and rebuild 2-3 engines a week EVERY WEEK and see most every oil out there and how they perform or how they don't... I've always said that 90% of all outboard engine failures are not due to the lack of oil quality.... Most failures are from mechanical issues. Due to heat, timing, and or fuel quality or the lack of fuel...
I'm from the old school and like what I see when I tear down a motor that has been ran on Pen, Red Line, Motol, or Merc and like a "WET" engine at time of tear down , I've never thought that robbing a motor of lubrication can or will increase HP... I also can look at a piston and smell of the residue and tell you what kind of oil was used. Just have been doing it so long.
I have witnessed some oils peel the chrome right off a crank and bearings so dry they are blue and the rings so sharp you can shave with them. And some have accult like followers . There are some that are in love with the way an oil smells not knowing or caring how well they are lubricating their engines.
Hope I've answered your question, I'm not posting entertaining an oil war discussion , I tell people run what you choose but if you choose wrong here's my card ...
Cheers,
Jay
