Enertech Thaw-It is the product you reach for when it is already too late, when your diesel has gelled or iced up and your engine will not run. It is an emergency rescue treatment, not an everyday additive, formulated to dissolve the wax and ice crystals that clog your fuel system in cold weather and get your fuel flowing again. Used as directed, it starts working in about 20 minutes to re-liquefy the fuel throughout your system, so you can get back on the road or back to work. It is safe for diesel and biodiesel, works with #1, #2, #4, and #6 fuels, and contains no chlorinated solvents, methanol, or harmful alcohols. If a cold snap has left your truck or equipment stranded with gelled fuel, Thaw-It is the fast, no-nonsense fix to keep in the cab all winter.
Key Benefits
- Rescues gelled or iced fuel - An emergency treatment that dissolves the wax and ice crystals blocking your fuel flow, so you can get running again.
- Works fast - Begins working in about 20 minutes when used as directed, helping restore fuel flow throughout the entire system.
- Handles ice and water too - Breaks down and disperses the ice and water in your fuel system, not just the wax.
- Safe, versatile formula - Works with diesel and biodiesel and #1, #2, #4, and #6 fuels, with no chlorinated solvents, methanol, or harmful alcohols.
Feature & Benefits
When diesel gets cold enough, the wax naturally in the fuel crystallizes and clumps together until it gels and stops flowing, and any water in the system can freeze into ice. Either one will plug your filter and fuel lines and shut your engine down, usually at the worst possible time. Thaw-It uses a special blend of organic and petroleum co-solvents to dissolve those wax and ice crystals and re-liquefy the fuel, breaking up the blockage and getting fuel moving through your system again.
It is built to be both effective and safe for your equipment. Thaw-It works with both diesel and biodiesel, is safe to use with #1, #2, #4, and #6 fuels, and it leaves out the harsh chemistry you do not want in your fuel system, with no chlorinated solvents, methanol, or other harmful alcohols. As it works, it also helps break down and disperse the water in the system, which is often part of the problem in a cold-weather freeze-up. Keep a bottle on hand through the winter and you will have a fast fix ready the moment you need it.
Directions & Dosage
Thaw-It is for emergency use once your fuel has already gelled or iced. If you can, remove the plugged fuel filter and replace it with a new one. If you have to reuse the existing filter, pour out as much of the ice or gelled fuel as possible first.
- Fuel filter: Fill the filter with a 50/50 mix of Thaw-It and diesel fuel. Do not fill the filter with 100% Thaw-It.
- Fuel tank: Add 32 oz of Thaw-It for every 50 gallons of fuel.
- Wait: Give the treatment about 20 to 30 minutes to work.
- Restart: Start the engine and let it warm up before you drive or operate the equipment.
Important: Thaw-It is meant for emergency use only, when fuel has already gelled or iced. It is not designed for regular, continuous, or preventative treatment. For everyday cold-weather protection that keeps fuel from gelling in the first place, use Enertech Polar Flow or another preventative fuel treatment. Always follow the directions on the product label, consult the Safety Data Sheet (SDS) for handling information, and dispose of product and containers according to local, state, and federal regulations.
Terms to Know
- Gelling - When cold weather makes the wax in diesel clump together until the fuel stops flowing and plugs the filter and lines.
- Fuel line freeze-up - When water in the fuel system freezes into ice and blocks fuel flow.
- Co-solvents - The blend of solvents in Thaw-It that dissolve both wax and ice to get fuel flowing again.
- Biodiesel - A renewable diesel fuel, often blended with regular diesel. Thaw-It is safe to use with it.
- #1, #2, #4, #6 fuels - Different grades of fuel oil and diesel. Thaw-It is safe to use across all of these.
- Preventative treatment - An additive used before cold weather to stop gelling from happening. Thaw-It is a rescue product, not a preventative, so pair it with Polar Flow for prevention.
