More about gelling and how to use

Diesel Winter Anti-Gel provides “Premium Diesel” qualities to standard diesel fuels in terms of detergency, stability, lubricity, winter operability, and cetane number. Diesel fuel contains wax, as temperatures drop these wax crystals clog fuel lines and cause problems for diesel engines. Our effective anti-gel additive greatly improves cold temperature performance and helps prevent the wax in the fuel from clogging lines. Additional properties provide further winter protection against freeze-ups. In addition, Diesel Winter Anti-Gel contains a powerful cetane improver for quicker cold starts and a maximum boost in power and performance. Diesel Winter Anti-Gel is recommended for ALL diesel engines.

Diesel Winter Anti-Gel should be used in every fill-up during the cold winter months. Recommended treatment rates are 1:1000 for #2 diesel.

The sulfur content of this diesel fuel additive does not exceed 15 ppm. This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines.



No other diesel oil or fuel additive has a better guarantee than Hot Shot’s Secret products. If our products do not deliver as promised, then we will give you your money back. End of story.

    5 out of 5 Freeze in bulk tank ?

    Michael Brooks

    Yes, I live in S.E. Missouri and I pull campers out of Indiana year round. My 95 gallon bulk fuel tank in the back of my pick-up, does not circulate like a regular factory truck tank to keep from freezing ( I turn on toggle switch to add to truck tank) will this help keep me from freezing up ?? I use the summer EDT and really like it.

    Jeremy (verified owner)

    We have three diesel pickups and several other Diesel engines. We also live in a colder climate, this fuel treatment has done a better job for us than the others we have used. We have not had an issue for two winters.

    5 out of 5 AMAZING PRODUCT !!!

    Chris HILL (verified owner)

    I run Peterbilt 387 trucks and live in Colorado, every year my truck would gel up and keep me from running until I found Hot Shot anti- gel. Last year I ran the whole winter without ever gelling up. I have tried every product on the market without success until I found this one. Hot shot keep up the good work.

    I have visited your website countless times and find that your customer service representatives, in particular Bo, to be very informative, patient, and professional. The crew has led me down what appears to be the correct path.I had a problematic Duramax LLY engine. Between Bo and your Diagnose your Diesel page i was able to successfully diagnosed a glow plug issue. This saved me money as for nearly every diesel shop in the Denver, Colorado area tried to sell me a $4000 plus fuel injector issue. Thank you to the entire Hot Shot crew and business. Now for a product specific accolade. I’ve ran your Every Day Treatment for two tanks but had to change out to your Diesel Winter Anti-Gel for the last tank due to sub-zero temperatures. I just started my 2004 Silverado and took it for a spin on wet streets (yes it warmed up past freezing). i cannot describe the performance improvements other than saying had I been a police officer, I would have had to give myself a ticket. At 1/4 throttle, I broke traction (water helps but not that much) and accidently took the truck at about a 45 degree sideways spin. I could hear the turbocharge spool up faster and it even whined that good whine. The truck runs like I put in a high performance engine. I know performance through my hot rodding days and this is performance. Is it the Cetane Booster or the lubricant or both? It just works fantastic. I can’t wait to try out your Stiction Eliminator and Diesel Extreme products! I will use these products on my family of gasoline and diesel vehicles. BTW: Thanks again Bo Signed Arkansas Hillbilly_

Frequently Asked Questions About Diesel Winter Anti-Gel

You count on your diesel anti-gel additive to keep your engine running in cold weather conditions, so you want to choose a product you feel confident will perform to your expectations. To make an informed purchasing decision, review the answers to some common questions about Diesel Winter Anti-Gel. You can also reach out to our team online for additional information.

How does Hot Shot’s Secret Diesel Winter Anti-Gel work?

Diesel Winter Anti-Gel works to improve winter operability using three different chemicals — a wax modifier, a wax anti-settling agent and a military-grade de-icer. The wax modifier significantly reduces the point at which wax in diesel fuel solidifies, and the wax anti-settling agent keeps the wax dispersed once the precipitation temperature is reached. Finally, the de-icer disperses moisture, preventing it from clogging and freezing fuel filters in temperatures as low as -40 °F.

The recommended treatment ratio for Hot Shot’s Secret Diesel Winter Anti-Gel with #2 diesel is 1:1,000. Therefore, use approximately 1 ounce of anti-gel for every 8 gallons of fuel for the best results.

Will Diesel Winter Anti-Gel work with my engine?

Our anti-gel formula is safe for use in all diesel engines, including marine, semitruck, construction, agriculture, RV and racing engines. Just a few popular engines Diesel Winter Anti-Gel effectively treats includes models from Cummins and Saab, GM’s Duramax and the Ford Power Stroke.

When should I add Diesel Winter Anti-Gel?

Diesel Winter Anti-Gel is the ideal fuel additive to use in cold weather when you want to improve cold starts, prevent gelling and icing, reduce fuel line freeze, boost cetane and improve fuel economy. Add one treatment of Diesel Winter Anti-Gel with every fill-up for consistent protection against low-temperature performance issues.

Please note that Diesel Winter Anti-Gel is intended for everyday cold weather use. For emergency situations in which fuel or fuel filters have already frozen, use Hot Shot’s Secret Diesel Winter Rescue.

Can I use Diesel Winter Anti-Gel with Everyday Diesel Treatment (EDT)?

Diesel Winter Anti-Gel provides all the same protections and benefits of Everyday Diesel Treatment -EDT with the addition of an anti-gel. All you need to use is Diesel Winter Anti-Gel.

Can I use Diesel Winter Anti-Gel with biodiesel?

We do not recommend using Diesel Winter Anti-Gel with diesel blends containing more than 20% biodiesel.

How should I store Diesel Winter Anti-Gel?

Once mixed with diesel, our anti-gel additive protects fuel to temperatures as low as -65° F. However, the freezing point of Diesel Winter Anti-Gel is higher before it is added to diesel. We recommend storing the product at a minimum temperature of 20°F for this reason. You should also take care to keep the product away from sources of ignition and always reseal the container tightly to prevent leaks. For more detailed storage and use information, see the official safety data sheet.

Will using Diesel Winter Anti-Gel void my engine’s warranty?

No, using Diesel Winter Anti-Gel will not cause damage to your engine or void your manufacturer’s warranty. That’s a guarantee.
