PLEASE READ BEFORE LEAVING STUPID COMMENTS: Running a normal 2 stroke engine of string trimmer on soy bean oil or vegetable oil. During the video it actuallu had a tiny bit of gas mix and motor oil in the tank with the Crisco, but afterwords I ran it several times over on pure Cisco oil. I said it was effeciant, but not so much. It intakes oil about twice as fast as it does gas, but it's still pretty cool. Use your imagination.
