13 wrz 2023 · When stored correctly, DEF can have a shelf life of up to two years. Factors such as temperature, light, and air exposure can affect its longevity. Ideally, the fluid should be kept in a cool, dark place, away from direct sunlight. Temperatures between 12°F (-11°C) and 86°F (30°C) are recommended.
Diesel Exhaust Fluid (DEF) has been required for the 2011 MY and forward diesel vehicles to meet 2010 EPA emission regulations. DEF is a non-hazardous clear fluid (67% deionized water / 33% chemically pure Urea) that is injected into the diesel exhaust system to reduce NOx emissions.
Typical shelf life of Diesel Exhaust Fluid (DEF) is 2 years. However, to maximize shelf life it’s recommended to store between 68°F and 23°F (20°C and -5°C). Several factors can play a role in reducing overall shelf life, so be sure to follow the recommendations below:
17 gru 2023 · Implementing a combination of optimal storage practices, consistent monitoring, and proactive maintenance can significantly extend the shelf life of DEF and ensure its effectiveness in reducing emissions from diesel engines.
Shelf life depends on the temperature of your storage facility. According to ISO22241 standards, ideal storage temperatures for DEF should be between 12°F and 86°F.
The following conditions are ideal for maintaining diesel exhaust fluid quality and shelf life during prolonged transportation and storage: - Storage temperature between -5. °C to 25°C [23°F to 77°F]. - Store in sealed containers to reduce the possibility of contamination. - Avoid direct sunlight.
The shelf life of DEF can depend on its storage conditions, but generally, it lasts one to two years. Once expired, it’s less effective and can lead to issues with equipment and machinery. You should find the expiration date of your DEF clearly marked on its container.
