Question about a 1980 Arctic Cat? 2 cycle injection?

I just picked up a 1980 Arctic Cat Trail Cat 3000 F/C. I really don't know anything about snowmobiles so this could be an easy one. It is oil injected. Is there a difference between "regular" 2 cycle oil and a 2 cycle that is meant for a sled with the oil injection. Any help is appreciated.
