I put in Pennzoil Hi-Vis 80W-90 Lower unit oil in the lower unit and ran the boat 3 outings over the course of 2 weeks. A total of about 6 hours runtime on this oil that is shown in the photo. Draining this oil which went in as a honey color, came out green!? I poured this oil into a jar and let it settle out, the next day I had a layer on the bottom of that was discolored and up top was green. No water ever showed its pretty face but I took the boat to the repair shop, had the lower unit pressure tested and all tested good !? Whattttttt

I wanted to share my experience with not using the OEM recommended oil. My service manual calls for "OMC/Johnson Hi-Vis Lower unit oil" it does not call for any weight or spec. Pretty illegal actually, but this is the service manual mean't for a johnnyrude tech so they can call for their own products at a shop i suppose. Still a shady practice to not call for a spec.

The repair shop advised, do not use that oil ever again. They recommended Merc High performance 90 WT over the jonny rude oil for this older outboard. As the synthetic stuff is an overkill and costs more. Being as there was no water, the only conclusion is the oil was being whipped up (foaming). [links]
