Hot Shot's Secret Diesel Winter Anti-Gel Fuel Treatment, 1 Gallon | Treats 1,000 gallons. Prevents fuel gelling, improves cold starts, and boosts cetane.

If you drive a diesel in a climate where the temperature regularly drops below freezing, Hot Shot’s Secret Diesel Winter Anti-Gel isn't just an additive—it’s a protection against a stranded vehicle. Diesel fuel contains naturally occurring wax paraffins. When the mercury dips, these waxes crystallize and "gel," clogging your fuel filters and starving the engine. Hot Shot’s Secret solves this by lowering the Cold Filter Plugging Point (CFPP) of your fuel by up to 40 degrees F. This ensures your truck starts reliably on those bitter -20F mornings when untreated fuel would turn into slush. What sets this treatment apart from basic "emergency" thaws is its comprehensive formula. It includes High-Quality Cetane Boost: Improves cold starts and reduces "clatter." De-icers: Neutralizes moisture to prevent fuel line freeze-ups. Lubricity Additives: Protects the high-pressure fuel pump and injectors from wear. It’s much cheaper to pour a few ounces of this into your tank at the gas station than it is to pay for a heavy-duty tow and a heated garage bay to thaw out a gelled system. For anyone in the "Rust Belt" or high altitudes, it's a non-negotiable part of winter maintenance.

Excellent ... better buying larger quantities

It works great, my yanmar an my doosan diesel engine love it.

As shown in a YouTube video testing video, Hot Shots Secret is literally beating every single diesel anti freeze treatment on the market. It also beats each competing brand by a long shot (pun intended). Most of the brands come close to -10f and some scraping by -20f. The power service is the only one claiming to get close to -30F which I have tested before and it has stood the test. This however, can get as much as -60F. No where realistically should it ever get that cold but the peace of mind in knowing that a full gallon should last about one whole winter season in the midwest for a 30,000 mile vehicle is the best bang for anyone's buck. Buy it in the summer when prices are low and demand is minimal and keep for when the cold begins to settle (January-March).

First time i used this brand. I drove and parked in14 degree weather. My truck started up perfectly.
