Diesel Exhaust Fluid Tips

  1. Use high-quality DEF: It is essential to use DEF that meets the industry standards, such as ISO 22241-1, to ensure its effectiveness and compatibility with your vehicle’s SCR system. Look for DEF that is certified by reputable manufacturers.
  2. Store DEF properly: DEF should be stored in a cool and dry place, away from direct sunlight and extreme temperatures. Ideally, it should be stored between 12°F (-11°C) and 86°F (30°C). Exposure to heat or freezing temperatures for prolonged periods can degrade the fluid’s quality.
  3. Handle DEF with care: When handling DEF, avoid contamination by using clean, dedicated equipment. Do not use funnels, containers, or pumps that have been in contact with other fluids, as contaminants can compromise the fluid’s integrity. If DEF comes into contact with surfaces, wipe them clean to prevent crystallization.
  4. Maintain DEF levels: Keep an eye on the DEF gauge or warning system in your vehicle’s dashboard. Refill the DEF tank before it runs out to avoid any interruptions in your vehicle’s performance. Running out of DEF may result in the engine entering a reduced power mode or preventing the engine from starting altogether.
  5. Use the right DEF dispensing equipment: When refilling the DEF tank, use dedicated DEF dispensers or containers specifically designed for DEF. These ensure that only DEF is dispensed and minimize the risk of contamination.
  6. Be mindful of DEF shelf life: DEF has a shelf life of approximately one year, so it’s essential to use it within that timeframe. Containers of DEF typically have an expiration date printed on them. Ensure you rotate your stock to use the oldest DEF first.
  7. Be cautious when traveling: If you’re traveling with a diesel vehicle equipped with SCR, ensure you have enough DEF for the journey. Plan your refueling stops accordingly to avoid running out of DEF in areas where it might be challenging to find a supplier.

Following these tips will help you maintain the effectiveness of your SCR system and ensure your diesel vehicle remains compliant with emissions regulations.
