Review: 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.
Review: So far a good anti gell product. - I have used this in my diesel truck and farm tractor and so far the temperature in my area was 10 degree and both started up with no problem. I am leaning towards this product working to prevent gelling up. I think it is worth a try id you have a diesel truck or tractor

## Features

- 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.
