Your diesel-powered vehicle is a reliable and efficient mode of transportation, but it needs regular maintenance to keep running smoothly. One of the most important components for your engine’s health is Diesel Exhaust Fluid (DEF). DEF helps reduce emissions from your vehicle while keeping it compliant with environmental regulations. In order to make sure you’re never at risk of running out, it’s important to store your DEF in a safe and secure way. Whether you’re just starting to use DEF or have been using it for years, these three tips will help ensure that your supply stays fresh and usable.

1. Store At The Right Temperature:

DEF should be stored at a temperature between 12-32 degrees Celsius. Storing the fluid in temperatures below 0 degrees Celsius can cause it to freeze, damaging your engine and reducing its performance. If you’re storing DEF outside or in a garage, make sure that it is well insulated from direct sunlight and extreme heat.

2. Store Away From Direct Sunlight:

DEF can be damaged if exposed to direct sunlight, so it’s essential to store it in a dark and cool area. If you’re storing the fluid outside, consider investing in a cover or tarp that will protect your supply from UV rays. You should also ensure to keep the container away from heat sources such as furnaces and other appliances.

3. Use a Closed-Loop DEF Transfer System:

When transferring DEF from one container to another, it’s important that you use a closed-loop system. This will prevent contamination by keeping the fluid in its original container and only using hoses for transfer. If you’re buying pre-filled containers of DEF, make sure that they are sealed properly and have never been opened before. It’s also important to check the expiry date of your supply and make sure it is still usable.


As you can see, practicing good storage habits for your DEF will help ensure that you’re never at risk of running out or experiencing engine problems due to an expired supply.  Make sure to store your DEF at the right temperature, away from direct sunlight and use a closed-loop transfer system whenever you need to move or fill up containers. Following these tips will help safeguard your engine’s health and performance for years to come!
