It is not suitable for long-term outdoor exposure
Diesel fuel has a limited shelf life and is susceptible to contamination. The three main threats to diesel quality are hydrolysis, microbial growth, and oxidation. Diesel begins to degrade within 28 days of storage and can typically be stored from 6 to 12 months, or sometimes longer under optimal conditions. However, storing diesel outdoors for extended periods poses several challenges that can negatively impact its quality and shelf life.
Firstly, diesel is sensitive to temperature fluctuations. Prolonged exposure to extreme temperatures or sunlight can accelerate the degradation process, making it challenging to start engines and potentially damaging fuel systems. To mitigate this issue, it is recommended to maintain a cool tank, ideally around 20°F, and not exceeding 85°F. This can be achieved by investing in an underground tank or providing a canopy or enclosure to shield the tank from direct sunlight.
Secondly, moisture and water exposure are significant concerns for diesel fuel. When diesel comes into contact with water, it undergoes hydrolysis, a chemical reaction that breaks down the fuel. Moisture can enter the tank through condensation, leading to water droplets forming and mixing with the diesel. This creates favourable conditions for microbial growth, as microbes require water to thrive. These microbes produce acids that further degrade the diesel, clog tank filters, restrict fluid flow, and cause corrosion. Therefore, it is crucial to minimise the exposure of diesel fuel to moisture and water sources.
Additionally, the presence of contaminants can shorten the lifespan of diesel fuel. Contamination can occur due to factors such as high humidity, improper storage conditions, or the use of inappropriate fuel additives. Diesel fuel should be stored in a clean, dry, and cool environment to prevent contamination and prolong its shelf life. Regular checks are essential to identify any signs of degradation or contamination, such as water or sediment buildup, and to take corrective actions promptly.
In summary, while diesel fuel can be stored outdoors for a limited duration under specific conditions, it is not suitable for long-term outdoor exposure. The challenges posed by temperature fluctuations, moisture, water exposure, and contaminants can significantly impact the quality and effectiveness of diesel fuel over time. To ensure the longevity and optimal performance of diesel fuel, it is recommended to adhere to proper storage guidelines, utilise suitable fuel treatments, and implement protective measures to safeguard the fuel from environmental factors.
