Beef tallow biodiesel has high lubricity, a high cetane number, and burns cleanly, reducing CO, particulate matter, and HC emissions. However, it has poor cold flow properties, which can cause fuel gelling in colder climates. These issues are resolved by using winter additives or blending with petrodiesel. The GlobeCore USB system ensures biodiesel meets cold flow and moisture content specifications, minimizing engine risks and ensuring safe use in unmodified diesel engines.
