Even a newer HPCR Diesel can work with vegetable oil, but if it's pre-heated (then getting thinner) there are better results. By the way, since hydrogenated oils, which get even thicker when cold, are widely used in restaurants due to their longer useful life, it makes harder to use it pure, but are not a bad feedstock for biodiesel...
