Hi there,
My perkins 4-236 owner manual asks for SAE 40 (Delo is one brand that I have heard is good to use). This seems to be a standard oil. Going to a standard automotive supply the 10-40w is way more common and won't wreck the motor immediately if that is all you can find.
Other engines have different requirements.
from your owners manual:
Use SAE 30 HD (CD) or 10W40 heavy duty diesel lubricating oil
