Yep. Any oil will work, really. I just always have 2t (or 2 cycle) around, and since that is what lubricates the engines internals, it just makes sense. You could use Crisco, if ya want, haha. You just want it to slide in relatively easily; it's a tight fit! You'll find with mopeds, there are more guidelines and suggestions than hard set rules. There is much improvisation, for sure. You learn to make things work.
