servicing rear derailler pulleys (derailleur)

I have read, watched videos but I am still unclear as to what to do. I have an ultra RerDer, about 2 years old with about 7k miles. I cleaned up my bike and ordered new pulleys over the winter but the new ultra pulleys didn't come pre-lubed, What should I do? In case you were wondering I believe they have ceramic bushings. Do they need grease or oil?

from experience, some do (BBB), some don't (KCNC), if you have got new ceramic ones, would expect them to come pre greased / not need any extra.

stock ultegra pulley is a ceramic bushing. oil or grease it depending on your maintenance interval preferences.

I clean mine on the bike when I service the chain. They get lubed when I lube the clean chain on the bike.
The Ultegra bottom pulley has a small ball bearing in it.

Thanks for all the help, actually they came dry and unlubed. I guess oiling them is easier than taking the plastic/ rubber bearing cover off and packing grease around them.
