PREVENTS GELLING: This 7-in-1 diesel anti-gel additive minimizes the size of wax crystals that form in diesel fuel during cold weather allowing the fuel to travel through the fuel filter at 20°F below the cloud point (wax solidification point).
ANTI-GEL FUEL BOOSTER: This product is designed to enhance diesel fuel in terms of lubricity & cetane. Improves lubricity up to 32% and 7 point cetane boost. EDT+ Winter Defense improves cold starts even in subzero temperatures.
DEMULSIFIES WATER: Effectively disperses moisture, plus protect your fuel system from rust & corrosion. It also prevents ice & fuel line freeze-ups, even in extreme temperatures as low as -40°F, providing reliable operation.
FUEL INJECTOR CLEANER: Cleans both internal & external injector deposits, enhances the lubricity of fuel to safeguard the fuel system components, such as the pump & injectors to increase engine longevity while also acting as a fuel system cleaner.
EASY TO USE: 16 oz bottle treats up to 200 gallons. Concentrated, use just 2oz per 25 gallons, double that amount in temperatures below 0°F. Start using near freezing temperatures. Just pour it into your diesel fuel tank during your next fill up.
POWERED BY SCIENCE: Our products are engineered to resolve issues, make equipment last longer and improve efficiency. Nothing leaves our building with our name on it unless we know it is absolutely the BEST it can be.

Works well, no complaints.
I have had no issues with winter time running of diesel engines. Not sure if it does what all it claims, but I have no complaints and seems to do the trick. I had used PS and think it is a great product, but this seems to winterize just as well and should have other benefits along with the winterizer.

Diesel Truck
I’ve been using Hot Shot’s Secret Everyday Diesel Treatment in my Ford F250, and I couldn’t be happier with the results! This treatment has made a noticeable difference in the performance of my truck. It helps improve fuel efficiency, reduces engine noise, and keeps the fuel system clean. My truck runs smoother, and I’ve noticed a slight improvement in acceleration.The 16-ounce squeeze bottle is super convenient and easy to use—just squeeze the right amount into the tank, and you’re good to go. I love how it’s designed to be used with every fill-up, making it simple to maintain the health of my engine. Plus, it’s great for combating the harsh effects of diesel fuel, especially in colder weather.Overall, this is a must-have for any Ford F250 owner who wants to keep their truck running in top condition. It’s affordable, effective, and easy to use.

Prolong the life of your exspensive fuel system
I use this stuff every fill up in the winter time on my 05 cummins. Although I don’t have to worry about gelling necessarily, this product still provides the lubrication and cutane boost that prolongs the life of a diesel fuel system. Fuel systems aren’t cheap and this small additional cost is worth the investment.
