I think that as long as you're not going to be running the stuff as your primary fuel for an extended period of time you'll be fine. The only potential issue I can see is the emulsifier and that is so small a fraction it's probably benign. If it were me, I'd use it in small doses, maybe 20% mixed with diesel. And I'd also run 2% two stroke oil just to keep the lubricity up in case the emulsifier has some adverse effect there.

Free fuel is always a good thing.
