Hi, I work with Air1 (a Diesel Exhaust Fluid manufacturer) which
supplies DEF to the US. It's not just any urea but a high spec urea
solution which is used to reduce NOx emissions in high powered diesel
engines. If normal grade urea is used instead of DEF, the system will
suffer as its not pure enough. DEF can be bought in different pack
sizes from 1 gallon to bulk storage. When on the road, usually you
can fill up at DEF retail outlets, local fuel/lubricant distributor
as well as a local dealership.

We see that a lot of people have questions about DEF, and are helping
to answer them. If there are other DEF questions, or extra
information needed, I'm happy to answer any questions on this topic.

ok, here's a question: what exactly is "high spec urea solution".

Good question! DEF is a high spec urea solution which means that it is
made from high purity urea and demineralised water. The specification
is defined in an internationally recognized ISO standard, which means
that there are strict limits for acceptable levels of potential
impurities, and accurate concentration of the DEF solution. If it’s
not within this specification, it is not DEF. The reason for it
being of a specific high standard is due to it being injected
through the SCR system. If low grade urea and tap water is used it
could cause SCR catalyst deactivation, and system breakdown.
