Premium Performance Meets Ultimate Cold Weather Protection
Don’t let dropping temperatures leave you stranded. Hot Shot’s Secret EDT + Winter Defense takes the industry-leading formula of their “Everyday Diesel Treatment” (EDT) and fortifies it with a powerful anti-gel agent.
This is the ultimate “one-and-done” winter solution. You no longer need to buy a cetane booster and an anti-gel separately. This bottle does it all: it prevents your fuel from gelling in sub-zero temperatures, boosts your cetane for faster cold starts, and protects your fuel system with LX4 Lubricity Extreme.
Whether you are driving a modern CP4-equipped truck or a legacy diesel, this additive ensures your rig starts easily and runs smoothly, no matter how low the thermometer drops.
Key Features
-
Superior Anti-Gel: Lowers the fuel’s Cold Filter Plugging Point (CFPP) and Pour Point, preventing wax crystals from forming and clogging your fuel filters in temperatures as low as -40°F.’
-
Boosts Cetane (Up to 7 Points): Higher cetane means faster combustion. This is critical in winter, providing quicker cold starts, smoother idling, and improved fuel economy
-
LX4 Lubricity Extreme: Infused with Hot Shot’s premium lubricity agent to protect sensitive fuel pumps and injectors from wear—vital for low-sulfur diesel fuel.
-
Moisture Control: actively disperses moisture to prevent water from freezing in fuel lines and filters (and prevents rust/corrosion).
-
Cleans Injectors: Keeps nozzles clean to maintain efficient spray patterns and power.
-
Warranty Safe: Does not void manufacturer warranties and is safe for all diesel engines (including those with DPF/DEF systems).
