Hot Shot’s Secret Diesel Winter Anti-Gel Fuel Treatment 1 Gallon – Treats 1000 Gallons – 7-in-1 Diesel Fuel Additive, Prevents Gelling, Improves Cold Starts, 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.

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

Works as advertised!

Good product. Use these all winter long, no issues even though we had -10 Fahrenhait.

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).

I use this product on my 2019 Ford Super Duty. I live in North Dakota (which without a doubt has sustainable stupid cold temps for weeks to months on end). So far this year I have been able to run #2 fuel and the correct 4 oz dosage per fill up and have not gelled up. I have not gained any mileage whatsoever, but the added lubricity and the ability to run #2 year round gives great peace of mind. Why only 4 stars? this is a full gallon container - not only is the shape of the bottle difficult to pour into the fuel tank, but it is incredibly difficult to measure the appropriate size dose as well. For how expensive this stuff is, I’m not going to settle for just throwing a splash in and calling it good. You will want to purchase a separate measuring container to pour this stuff into and put in your truck. I also put about half a quart of 2 stroke oil in during harsh winter months to add more lubricity as well. Anyhow; buy this stuff, buy a measuring container and enjoy lower fuel costs and added reliability to your diesel.

Great winter fuel treatment for our Ford F350 Diesel.

Works for Canadian winters. Got no issues. Didn't help with fuel economy but serves the purpose of antigel
