Hot Shot's Secret Diesel Winter Anti-Gel Fuel Treatment 1 Gallon – 7 in 1 Fuel Booster Winter Protection, Diesel Additive Prevents Gelling, Improves Cold Starts, Boosts Cetane (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).

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

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

Great winter fuel treatment for our Ford F350 Diesel.

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.

Saw a review online comparing 7-8 different anti-gel fuel treatments and they looked at several factors, this was rated number 1... I decided to try it out and bought some Dec when we had the cold spell in Eastern Washington (lowest was -26F)...I drive the same route and distance 5-6days a week for work and from day one I went from low 16 MPG average to over 19MPG average, and 22-23MPG for the highway trips...That includes the key-less start every morn...Been using 4oz per tank full ever since w/ consistent results... 2014 2500HD Silverado 4x4 stock 2016 2500HD Silverado 4x4, stock

I have 5 diesel trucks, use this in them all, and the winter anti-gel even in all my red diesel for my construction equipment, can’t ask for better. Only complaint (though still 5 stars) is they sell it as a 1 gallon like the summer blend but it comes in two 1/2 gallon jugs. It works the same, just easier to misplace them for me. I’m sure I have 4-5 of these 1/2 gallon jugs sitting around places and have to keep reordering it because I lose track of the 2nd bottle then by the time the new order gets here I find it. The smaller bottles. Not the one time use but the one with the measuring thing in it leaks, I love those, and wish they didn’t as I’d get those even though they are more expensive for the tool box but they always leak immediately. Wish I had an easy way to measure. As right now I just “guess” and I a mm 100% sure I do a 2x or 3x dose.

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

This is a wonderful product that does what is says!

I even tripled the dose to help at -35 and it still acts like ive put nothing in it at all. left me stranded twice now. The cheap stuff i put in it worked 100x better. A poor product and frankly dangerous as it could leave someone stranded in minus 40 degree weather.
