Hot Shot's SecretDiesel Winter Anti-Gel– 16 Oz Squeeze, 7-in-1 Diesel Fuel Additive – Prevents Gelling and Fuel Line Freeze-Ups – Boosts Cetane – Cleans Injectors – Improves Performance, Amber

I was using the Ford cetane additive and switched to this at the recommendation of my son who is a diesel mechanic. I don't know if it is any better, but it sure is a lot easier to use. I am now a full-time user. I also think it helps the mileage over not using any cetane.

Great product

Increased my mileage to at least 4 miles to the gallon on the highway.

I run a small trucking company and this is all we use in our Freightliner Cascadia's. It doesn't reach single-digit temperatures where we operate but it does get into the teens. This anti-gell is fantastic. We have never had issues with cranking our engines or our fuel gelling up. The engine sounds great as well, no rough idling. My only complaint is that this is a squeeze bottle and it gets a little annoying to have to squeeze then pour in the liquid from the top but that's a very minor inconvenience. All in all, fantastic product. Hotshot's Secret is all we use in our Semi Trucks and for good reason!

Just what was needed to get the tractor ready for winter .

I got this additive after watching YouTube videos and testimonials from forums. I used to use Howes Anti Gel but decided to go with this stuff. I drive a 2016 Chevrolet Duramax so I want to help keep the fuel clean and as lubricated as I can to help keep my CP4 from going out and ruining my fuel system. The jug itself is super easy to use and seals off nicely and doesn't leak. I use this at the higher rating every time I fill up. I will probably start using it in all of my equipment as well.

Use on a 2005 5.9 cummins with a DFC street series long block, all new fuel system. Hoping to preserve the fuel system as much as I can! I would not advise keeping this stored inside your vehicle but if you have to, keep it standing upright or it will leak and stain and smell horrible.

Buy it every winter every fill up
