Aren Johnson and Evinrude outboard oils the same?
It was until a few years ago. The Evinrude oil now is a synthetic blend, designed specifically for the Evinrude Ficht direct injected engine. It has extra detergents which magnetically suspend carbon molecules so the the engine can expel them instead of letting them stick to the piston. Although It is recommended for the Evinrude Ficht, it can be used in all outboard motors.
