Hot Shot’s Secret™ Introduces Next Generation Diesel Exhaust Fluid – Ultra Premium DEF™
Cleans and prevents crystal buildup, restores performance, and clears fault codes
Mt Gilead, OH (September 1, 2026) – Hot Shot’s Secret™, the fastest-growing performance chemical brand in the USA, introduces Ultra Premium DEF™, a next-generation diesel exhaust fluid with patent-pending additive technology that stabilizes the fluid, helps clean the SCR system, and protects it from crystal buildup. The first rollout of Ultra Premium DEF will begin soon at O’Reilly Auto Parts stores nationwide.
SCR-related fault codes can cause downtime, lost revenue, and costly repairs. When used as directed, Ultra Premium DEF improves reliability, provides long-term Selective Catalytic Reduction (SCR) protection, and can clear many DEF/SCR OBD trouble codes, including P20EE, P20EF, P204F, P207F, P20E8, and P218F.
“Innovation has always been at the heart of Hot Shot’s Secret, and we had no interest in bringing another commodity DEF to market,” says Hot Shot’s Secret Brand Manager Josh Steinmetz. “Our team saw an opportunity to do something better. By incorporating our patent-pending Premium DEFender™ technology directly into the fluid, we created a product designed to help protect the SCR system while supporting long-term performance and reliability.”
As an API (American Petroleum Institute) certified DEF, Ultra Premium DEF is recommended for any diesel vehicle or equipment with an SCR system, including pickups, cars, vans, semi-trucks, agricultural and construction equipment, and industrial applications. Made with high-grade synthetic urea and triple-filtered for purity, it exceeds industry standards for DEF fluid.
Lubrication Specialties President Brett Tennar adds, “While most know Hot Shot’s Secret for fuel and oil additives, we actually develop a broad range of products – oils, specialty products, greases, and maintenance solutions. This expertise gives us a unique understanding of diesel systems and why we’ve earned the reputation as ‘The Diesel Experts.’ This launch reflects the hard work and dedication of teams across our company, and we are very excited for our partnership with O’Reilly Auto Parts to bring this innovation to diesel owners nationwide.”
