Before purchasing DEF from a distributor or from the pump, it’s important to ask a few questions:
Does The DEF Manufacturer Follow Industry Standards?
In short, not all DEF is created equal. While the basic chemistry of DEF is the same, the manufacturing process can make a difference in its quality. Look for a manufacturer that holds API (American Petroleum Institute) DEF certification. You also want a manufacturer that meets international specifications, specifically ISO standard 22241. By meeting these standards, you can be assured the manufacturer is maintaining quality standards in manufacturing, handling, testing, and storage.
What Is The Manufacturing Date Of The DEF?
Generally, DEF has a shelf life of between one and two years. However, the exact shelf life depends on the ambient temperature in which it is stored. If the ambient temperature is kept between 10 and 90 degrees, the shelf life is at least a year. If temperatures do not exceed 75 degrees, the shelf life can be up to two years. Now, in a hot Southwestern summer, temperatures can get well above 100 degrees. While this will not affect DEF in the short term, it can cause problems if kept in those conditions for an extended period of time.
How Is The DEF Stored?
DEF needs to remain in a pure state to run efficiently. To ensure the fluid remains as pure as possible, DEF must be stored in a specialized container and use specialized dispensing equipment. It is also important for the DEF to be kept in a cool, dark location to prevent evaporation or premature spoiling of the urea.
What Size Containers Of DEF Do You Offer?
Semi-truck drivers will want to pump DEF directly into their vehicle. A fleet manager may want 55 gallon drums for dispensing. A pickup truck owner may want a 2 gallon jug on hand. Ask the distributor what size containers are available.
