DEF 50%

Is a concentrated solution designed for use in off-road and heavy-duty vehicles. It contains a higher concentration of urea, which allows for longer intervals between refills, and may require specialized pumps and dosing systems.

DEF 32.5%

Is the most common DEF solution, suitable for use in most diesel engines. It requires more frequent refills than DEF 50%, but is compatible with standard dosing systems and equipment.
