In Parashah Tetzaveh, we read about Moshe being told by the Holy One, blessed be He, that when the cohanim are consecrated, that blood from the second ram should be mixed with oil and sprinkled on Aharon and his sons. Is this oil regular olive oil or is it the holy anointing oil?

It is the holy anointing oil, comprised of olive oil together with specific spices, see Shmot 30, 22-33.
