Black Oil in Keel - Every year

[higrader]

Hi Guys - first time here. I change the keel oil on my 2018 E-Tek 30hp at the end of every Summer with Envinrude oil. It goes in Golden, comes out black as night. For first 3 years it was on the 3 year no touch service schedule, and the dealer had no problems with the color, but I have my doubts with it. I have an 8yr warranty and on yr 6 this coming summer. Does anyone see an issue with this color? - Thanks

No issue at all.
