Cod liver biodiesel performs similarly to other marine and vegetable oil biodiesels. It has low sulfur, good cold flow, and high lubricity, leading to reduced engine wear and emissions. However, due to high PUFA content, it may have slightly lower oxidative stability, affecting storage and long-term use. Cetane numbers are moderate. Emissions of CO, HC, and PM are lower, but NOx may be slightly elevated. The GlobeCore USB system produces clean, stable biodiesel that meets fuel standards, ensuring safe engine use.
