The amount of oil required as been an ongoing argument for far too many years. Here’s some info from my 1973 Evinrude Mate, note that they spent 3 valuable pages discussing their thoughts on the amount of oil required. They are pretty specific about the old SAE 30 oil that was only available in the 1950’s, before TC-W oil became available. Of course the problems caused by too much oil are not as bad as using too little, and cheap oil may only save you money in the short term. I understand your concerns for the environment and dumping oil in the lake is frowned upon. Do what makes you feel comfortable, after all it is finally the owner’s decision. Don’t forget to fog the motor before storage to prevent corrosion inside.
