What should be done if fuel quality tests reveal contamination?

When fuel quality tests indicate contamination, the most appropriate action is to immediately dispose of the contaminated fuel and clean the tank. Contaminated fuel can lead to a variety of serious problems, including engine damage, reduced performance, and increased emissions. By removing the contaminated fuel and thoroughly cleaning the tank, you prevent any future complications that may arise from using fuel that does not meet quality standards.

This proactive approach ensures that fuel systems operate efficiently and safely, helping to maintain equipment reliability and effectiveness. It is critical to address contamination promptly rather than continuing to use or attempting to mix contaminated fuel with clean fuel, as doing so could exacerbate the issue and introduce further risks to the engine or system.
