Hot Shot's Secret Diesel Winter Anti Gel 1 Gallon, Amber (P403301G)

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).

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

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

This is a wonderful product that does what is says!

First year using this in a 2020 Ford 6.7 diesel and a 23 Ford 6.7 HO diesel. For measuring we wen to Walmart and bought a ketchup dispenser that has the ounces on the side, the rubber does not deteriorate and others have used it and it's worked great for us so far. Will get a new one each season since they're only a dollar each. We just pour the anti-gel into the ketchup dispenser so we have a easier way to measure. We've gotten weather down to -2 which is cold for us coming from CA, no issues with our fuel whatsoever but we also use hot shots during non-winter months. Definitely recommend it and buying it by the gallons. A lot easier to last you through the winter
