Re: Shell Nautilus Hi-Per Synthetic safe for outboard?
If I am not mistaken..I think the oil for personal water crafts is a different oil.. not for outboards....outboard oil has to be TW-C3 classified for outboards....
Re: Shell Nautilus Hi-Per Synthetic safe for outboard?
they make synthetic outboard oil......Pennsoil and also Evinrude X-50....they have a blend also....by Pennsoil.....I my self run the Evinrude X-50..it has a de carb agent in it and my motor runs nice with it..no smoke or smell
Re: Shell Nautilus Hi-Per Synthetic safe for outboard?
Mercury makes a synthetic too..and Yamaha does also..they are all good oils.....just know that they dont come cheap..but to me its worth the price if my motor runs this good...and stays clean
