In the context of fuel quality, what is one hazard posed by commingled fuel?

Commingled fuel refers to a mixture of different types of fuel or fuel that has been combined from various sources. One significant hazard posed by commingled fuel is inconsistent quality. Different fuels can have varying chemical compositions, properties, and performance characteristics. This variability can lead to challenges in engine performance and efficiency, as well as potential damage to engines or equipment that are not designed to handle such inconsistencies.

For example, if gasoline and diesel are accidentally mixed, the resulting fuel may not perform adequately in engines designed specifically for one type of fuel. Additionally, variations in the presence of additives or contaminants can further compromise fuel quality, affecting combustion efficiency and leading to increased emissions or engine knock. Therefore, the key issue with commingled fuel is that it can result in a lack of predictability in performance, which can be detrimental to both the equipment being used and the overall fuel management practices.
