Finding high quality diesel exhaust fluid (DEF) near you shouldn’t be a hassle. If you are a long-haul truck driver or drive a diesel vehicle, we have DEF filling stations designed to meet your needs. Our diesel fuel lanes and gas station convenience stores offer diesel exhaust fluid. Come to us when you are looking for DEF nearby.
If you are a motorist using diesel fuel, most of our gas station convenience stores stock 2.5-gallon jugs of DEF. If you are a professional truck driver, 98% of our locations have bulk DEF pumps. These pumps are right at our diesel fuel lanes, making it easy to fill your DEF tank. If you are an UltraONE member, you can even earn rewards on your DEF purchase!

Understanding Diesel Exhaust Fluid (DEF)
DEF is essential to the selective catalytic reduction (SCR) system in modern diesel engines. Using diesel exhaust fluid, the SCR system converts nitrogen oxide (NOx) into nitrogen and water. This greatly reduces the amount of emissions released by diesel engines and ensures your vehicle complies with emissions regulations. This is why we've worked hard to enhance our network by making DEF available at the pump!
Why DEF is Important
DEF is vital for maintaining the performance of modern diesel engines. It helps in:
- Reducing Emissions: DEF breaks down harmful NOx emissions into harmless nitrogen and water.
- Improving Engine Efficiency: Using DEF can lead to better fuel economy.
- Compliance with Regulations: Many regions require vehicles to meet specific emissions standards.
