UOA for my boat for its annual oil change. Did it out of curiosity more than anything else. Boat is 16 years old and engine/drivetrain is original. Raw water cooling used in fresh water only.
Not sure I'm that concerned with iron number, the boat does sit for about 8 months per year unused. I do not fog it in the fall so I suspect rust does form over the winter.
The viscosity is frighteningly low. This year I put in Chevron Delo 400 SAE 30 oil but frankly after looking at the viscosity of this Volvo stuff, I might just use an HDEO 15w40 from now on.
