Diesel Fuel Longevity Guide
Causes of Diesel Fuel Degradation
- Heat
- Moisture (which may lead to fungal and microbial growth)
- Air exposure
- Biodiesel blends, which have hygroscopic properties and attract moisture
Signs of Fuel Deterioration
- Cloudy or darkened fuel appearance
- Unusual sour odor
- Presence of sludge or sediment
- Poor engine performance or clogged filters
Prevention and Maintenance
- Regularly drain water from storage tanks (at least once a month)
- Use biocides and fuel stabilizers as recommended

Key Takeaway: Proper fuel management from the start helps reduce risks and control long-term costs.
