DEF Frequently Asked Questions
What is Diesel Exhaust Fluid Made of?
Diesel Exhaust Fluid (DEF) is a solution composed of 32.5% urea and 67.5% deionized water. It is used in diesel engines to reduce the amount of nitrogen oxide (NOx) emissions. DEF helps meet environmental regulations by converting NOx into harmless nitrogen and water vapor through a process called selective catalytic reduction (SCR).
How Does Diesel Exhaust Fluid Do?
DEF is injected into the exhaust system of a diesel engine, where it mixes with the hot exhaust gases. The urea in DEF breaks down into ammonia and carbon dioxide, which then reacts with nitrogen oxide in a catalytic converter to form harmless nitrogen and water vapor. This process reduces harmful emissions and helps diesel engines meet environmental regulations.
How Often Do I Need to Refill DEF?
The frequency of DEF refills depends on your vehicle's fuel consumption and usage. Generally, DEF tanks are designed to last between oil changes. On average, one gallon of DEF is consumed per 50-100 gallons of diesel fuel. It's important to monitor the DEF level indicator on your dashboard to avoid running low.
What Happens if I Run out of DEF?
If your vehicle runs out of DEF, the engine's performance will be affected, including limited power and reduced speed to encourage refilling. Most modern diesel engines will not start if the DEF tank is empty to ensure compliance with emission standards. Always keep a spare container of DEF to avoid inconvenience.
How Should DEF Be Stored?
DEF has a shelf life of approximately two years if stored correctly. It should be kept in a cool, dry place away from direct sunlight. Avoid exposure to extreme temperatures as it can affect its quality. Always check the expiration date on DEF containers before use.
Is DEF Affected by the Weather?
While extreme temperatures can affect the quality and shelf life of DEF, it is designed to function in a wide range of weather conditions. However, if the temperature drops below 12°F (-11°C), DEF may freeze and expand. It's important to ensure your DEF tank is insulated or stored in a heated area during cold weather.
