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

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

Buy it every winter every fill up

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.

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

Don’t forget when you buy fuel in the summer add anti jell. So you won’t have trouble in the winter.

If you ate looking for an anti-gel diesel additive, this is it, stop looking for better….you ain’t gonna find it. I did days, if not a month’s worth of independent research vetting all available anti-gel products, that also provide added protection (I am somewhat of a geek when it comes down to finding the best); this is it, trust me.

Good
