Hot Shot’s Secret Premium DEFender is engineered to clean and prevent DEF crystal buildup in your truck's fuel system.
Harmful deposits in the SCR system can reduce performance, increase fuel use, and lead to costly repairs or downtime. Hot Shot’s Secret Premium DEFender helps restore performance while protecting injectors, sending unit, tank and more.
The company suggests using Premium DEFender each time refilling DEF to prevent white crystallization deposits from forming.
Premium DEFender is triple-filtered for purity, and is ash and dye-free formula.
The product can be used in all SCR-equipped diesel engines including cars, trucks, semis and equipment, and will not void OEM warranties when used as directed.
Premium DEFender, which is compatible with all brands of DEF, can be purchased at most truck stops and travel centers, auto parts stores, farms stores and Walmart for $9.99 for an 8-ounce bottle.
