If you mean brand, most oil in a new engine is a "break in" oil, so trying to keep the same oil brand or type is unnecessary.
Use a good quality non-asphalt based oil that meets the grade and weight requirements for the engine. These requirements will be in your chassis manual.
For the best protection, go with a full or blended synthetic oil.
