This 16 oz bottle of Hot Shot's Secret Premium DEFender is blended to stabilize and lubricate DEF, reduce crystal formation in varying temperatures, and support reliable SCR operation when added at the recommended concentration.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this additive reduce crystal formation in DEF systems?\u003c\/h3\u003e\n\u003cp\u003eThe formula alters DEF properties to minimize the conditions that allow urea-based crystals to form and adhere to components. By keeping DEF more stable and less prone to crystallization, it helps maintain flow through dosing systems and prevents abrasive buildup on valves and sensors.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStabilizes DEF chemistry to slow crystallization.\u003c\/li\u003e\n  \u003cli\u003eReduces deposit adherence inside lines and injectors.\u003c\/li\u003e\n  \u003cli\u003eHelps during temperature swings that promote crystal growth.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan it help avoid DEF-related trouble codes and costly repairs?\u003c\/h3\u003e\n\u003cp\u003eWhile no additive can guarantee codes will never appear, using this treatment can lower the chance of crystallization-triggered faults that lead to codes such as P20EE, P204F and P207F.
