Two stroke engine synthetic oil can be used, from what our manufacture notes the highly recommend oil is Valvoline (Two Stroke Racing Oil). Another type of oil that our tech has recommend is Opti2 Ultra gray oil. The main thing is to make sure it is a 2 stroke engine oil rated for air cooled engines. Do not use oils that are used for 4 stroke engines or water type engines.
