Running stock Merc 500 HP’s and Bravo 1 drives.
Is the Shell Rotella’T Triple protection 15W/40W oil still good for the flat tappet cams?
Should I just stay with the HP Merc drive oil?
I don’t think that I need any exotic fluids since I am running mostly stock components.
Thank you for any help in advance.

Last time I checked, the Rotella had reduced levels of zinc to comply with the latest specs.
The Mercury 25w40 had a good slug of zinc last time I checked, also Valvoline VR-1 and Spectro Motorgard.
