  1. What is DEF and What Are its Dangers? DEF, or Diesel Exhaust Fluid, is a solution used to reduce nitrogen oxide emissions from diesel engines. It’s not toxic or flammable but should be handled carefully to avoid spills, eye contact, or ingestion.
  2. How Does DEF Work? DEF is injected into the exhaust stream of diesel engines equipped with Selective Catalytic Reduction (SCR) systems. It converts harmful nitrogen oxides into harmless nitrogen and water.
  3. Why Does My Equipment Need DEF? All Final Tier4 engines are equipped with SCR systems to comply with emission regulations and improve fuel efficiency.
  4. How Do I Use DEF? DEF should only be used in dedicated DEF tanks, not in diesel fuel tanks. These tanks are easily identifiable with a blue cap and smaller opening.
  5. How Much DEF Can I Expect My Equipment to Use? DEF consumption varies depending on the engine and application but typically ranges from 1-3% of fuel consumed.
  6. How Often Do I Refill DEF? DEF tanks are smaller than fuel tanks, so they require regular checks and refills, often with every fuel refill or every other refill.
  7. How Do I Store DEF?DEF should be stored in containers made from non-corrosive materials like stainless steel or polyethylene. It can be stored for up to one year but should be protected from extreme temperatures and direct sunlight.
  8. How Do I Know If My DEF Is Old or Contaminated? Check DEF for cloudiness or discoloration, which may indicate contamination. Proper disposal methods should be followed for old or contaminated DEF.
  9. How Much Does DEF Cost? DEF costs about the same per litre as diesel fuel but is not consumed at the same rate, so usage should be factored into cost calculations.
  10. Where Can I Get DEF? DEF is available at petrol stations, retail stores, and reputable dealerships. It’s important to ensure that DEF is API and AdBlue® certified for use in heavy equipment.
