What Causes Fuel to Go Bad? Understanding Fuel Degradation
Learn about the causes of fuel degradation, including oxidation, evaporation, and how to prevent it.
414 views
Fuel goes bad primarily due to oxidation and evaporation. Over time, chemical reactions with oxygen degrade the fuel, leading to gum and varnish build-up. Moisture can also enter the fuel, causing phase separation and microbial growth. To prevent this, store fuel in a sealed, moisture-resistant container and use stabilizers.
FAQs & Answers
- How long does it take for fuel to go bad? Fuel can start to degrade within a month if not stored properly, depending on the type and storage conditions.
- What can I do to keep fuel fresh? To keep fuel fresh, store it in a sealed container, use fuel stabilizers, and keep it in a cool, dry place.
- Can bad fuel damage my engine? Yes, bad fuel can lead to engine knocking, decreased performance, and potential engine damage due to debris buildup.
- What is phase separation in fuel? Phase separation occurs when water contaminates fuel, causing the water and fuel to separate, which can lead to engine problems.
