Which Extra Heavy Oil for Johnson Motor Wheel?

[TRoland]

The manual calls for extra heavy oil such as Mobil B, extra heavy Polarine, or Havoline. What do you run in yours or what is the modern equivalent?

Just use a good quality 2 cycle. oil.
Low ash 2cyl oils did not exist when these where built. Regular engine oils where used.
That is why 2 cycle engines would wear so bad and make such a mess running.

Aero shell 50wt is what I use in all my early (1922) Johnson outboards.The early Johnsons depended on a heavy oil and rich mix to not only lubricate,but to seal the crank bearings.
