first oil/filter change haul out next weekend

I have searched and read lots of threads here, it's been a great resource.
Boat is new to me this July

Starboard engine 1986 Crusader 900hours, Port 2012 Crusader longblock 400hours.
Fresh water cooled.

This is my plan before haul out.

For oil Rotella 15w40 (7 quarts per engine, realize I won't get it all out)

Filters Napa Gold 1515

Engine mounted fuel filters Napa Gold FIL 3271

RACOR 500 FG bulkhead mounted filters, 10 micron element.

Do I need any additives for the oil? Seems to be some zinc in the rotella oil.

Thanks.

You are best to check Rotella's data sheets for zinc content....our big blocks have been happy with the reduced zinc in Mobil 1 full synthetic....

depending upon where you are and how long the layup plan is, you will probably be better off adding some fuel stabilizer to the tank so it gets thru the system.....

Thanks, yes I have treated the fuel with startron.
