Nowadays there are even some researches about ways to provide it a lube system similar to a 4-stroke, avoiding the smoke-belching from the oil. Anyway, vegetable-based oils such as Castor oil are good options to cut the smoke since they get more effectively blended with the gasoline and eventually with some ethanol content (E5/E10/E15 or higher). It's worth to note that many synthetic oils have the same lube properties as Castor oil and palm oil.
