Store your vehicle in a climate-controlled garage or heated space. Use block heaters, small space heaters, or light bulbs under/around the engine to keep it warm overnight. Cover with tarps and circulate heated air if needed.

Mixing in kerosene lowers the freezing point of the fuel, delaying gelling. Be aware: this method can reduce fuel mileage and efficiency, and the blend must circulate enough to thaw any gel buildup.

Use Quality Fuel Additives

These additives alter fuel chemistry: preventing wax crystallization, improving cold flow, dispersing water, and maintaining lubricity. We recommend products like EDT+ Winter Defense (for daily anti-gel protection) and Diesel Winter Rescue. Good additives can drop your fuel’s Cold Filter Plugging Point (CFPP) and help avoid clogged filters in extreme cold.

When does diesel gel? And how can you protect your investment?

When temperatures drop, diesel fuel gelling can bring your hard-working engine to a standstill. Paraffin wax in the fuel starts to crystallize, clogging lines and filters — and stopping you in your tracks.

At Hot Shot’s Secret, we make products that work as hard as you do — no fillers, no fluff, just proven protection. Here are three simple, effective ways to keep your diesel running strong all winter long:

Use Heat

Store your vehicle in a climate-controlled garage or heated space.
Use block heaters, small space heaters, or light bulbs under/around the engine to keep it warm overnight.
Cover with tarps and circulate heated air if needed.

You don’t have to risk it when the temperatures drop. Combine heat, kerosene blending (if you choose), and high-performance additives to keep your diesel flowing no matter how cold it gets.

Real results from real people

“The Hot Shot products work just like Hot Shot says they do — even better than I would have expected. I have over 35 years’ experience in diesel truck maintenance as a mechanic, and for engine life longevity and minimizing the odds of problems, the Hot Shot program is part of my regular preventative maintenance.”
