Hot Shot’s Secret Premium DEFender is engineered to clean and prevent DEF crystal buildup in the SCR system, which can reduce performance, increase fuel use, and lead to costly repairs or downtime. The formula should be used each time DEF is refilled to prevent white crystallization deposits from forming. Triple-filtered for purity, the ash and dye-free formula is guaranteed not to void the manufacturer’s warranty when used as directed.
