Any reputable break in oil will be good . I used BluePrint motors brand only because it I ordered with the engine . On my flat tappet engines I usually use Driven HR1 or the HR2 oils. But for years I used off the shelf oils in my old cars never had an oil related failure

Shell Rotella T 10W30 Diesel Oil has high zinc.

Here is a chart from Speedway that shows some high zinc oils.

I got a case of Valvoline VR1, I need enough for 2 or 3 oil changes?
