What can untreated fuel contamination lead to?

Untreated fuel contamination can lead to injector failure and engine problems because contaminants in fuel, such as dirt, water, and microbial growth, can significantly hinder the performance of fuel injectors. These impurities can cause clogging, which restricts the flow of fuel and may result in uneven or inadequate fuel delivery to the engine. As a result, engine performance can deteriorate, leading to issues like misfires, rough idling, decreased power output, and ultimately, engine damage if not addressed. This situation can escalate to more severe problems if the engine continues to operate with contaminated fuel, highlighting the importance of fuel cleanliness for maintaining optimal engine functionality.
