Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Hot Shot's Secret Premium DEF Additive and Treatment is an 8 oz bottle designed to support the quality and reliability of Diesel Exhaust Fluid (DEF) in SCR-equipped diesel engines. This Premium DEF Additive and Treatment works with standard DEF to help maintain smooth exhaust-aftertreatment performance between fills.

What sets this DEF additive apart is its focused formulation from Hot Shot's Secret, crafted to support DEF stability and cleaner operation of your SCR system. When used as directed, it aims to minimize DEF-related hassles and protect sensitive components over time.

  • Maintains DEF purity by reducing contaminants that can interfere with aftertreatment performance.
  • Supports dependable SCR operation by preserving fluid quality during storage and use.
  • Compact 8 oz bottle is convenient for home, shop, or on‑the‑go maintenance in a fleet or personal rig.
  • Ideal for diesel-powered pickups, fleets, RVs, and off‑road equipment that rely on DEF systems.

Who it's for: diesel vehicle owners and fleet operators who rely on Diesel Exhaust Fluid to meet emission standards and keep exhaust systems running efficiently. This additive is particularly valuable for daily drivers with long trips, fleets managing multiple diesel assets, and anyone seeking an extra layer of DEF maintenance between refills.

Usage notes: follow the directions on the product label for your specific application. This additive is designed to be used with standard DEF; results depend on proper following of label guidance and vehicle manufacturer recommendations.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
