How can temperature fluctuations affect fuel quality?

Temperature fluctuations can significantly affect fuel quality primarily through the process of condensation, which can promote the growth of algae and other microbial contaminants. When temperatures rise and fall, it can cause moisture in the air to condense inside fuel tanks. This moisture then becomes a breeding ground for algae and bacteria, as these microorganisms thrive in the presence of water.

The presence of algae in fuel can lead to a variety of issues, including clogged filters and injectors, reduced fuel efficiency, and even engine damage if left unchecked. Additionally, algae can produce sludge that settles at the bottom of fuel tanks, further affecting fuel quality and system integrity.

In contrast, while other options may address various aspects of fuel dynamics, they do not capture the significant and detrimental impact that temperature fluctuations can have on water accumulation and biological contamination in fuel systems.
