Plant fuel oil is a solvent-blended fuel made from all plant oils such as peanut, rapeseed, cottonseed, and soybean oils. It is also an alcohol-free fuel; it burns without producing harmful emissions, leaving no smoke, odor, or residue. Moreover, it cannot be ignited with a naked flame, having a high flash point and high calorific value with a low freezing point [1]. Compared to methanol and the liquefied gas we used before, it is more fuel-efficient, saving about 20% of fuel. Overall, it is quite cost-effective. A fuel that burns longer indicates durability and cost savings, which is why many plant oils are popular among consumers.
