Hot Shot’s Secret EDT+ Winter Defense 8 oz – Treats 100 Gallons – 7-in-1 Anti-Gel Diesel Fuel Additive, Prevents Gelling, Protects Fuel System, Improves Cold Starts, Boosts Cetane

Works as it should and keeps the fuel from gelling even in 45 below wind chill Temps.

Has worked well so far. Seems to be high quality and it easy to use.

Winter Diesel Fuel Defense Works well and even better if you change your fuel line filters! Lesson learned, but will still use this product!

I have used this in my diesel truck and farm tractor and so far the temperature in my area was 10 degree and both started up with no problem. I am leaning towards this product working to prevent gelling up. I think it is worth a try id you have a diesel truck or tractor

Fixed my injector "nailing" problems on very cold mornings and improved overall driveability of my VW TDi

Good stuff but diesels have become an expensive maintenance thing and I just got sick of it so I traded my truck in who wants to have to drain a water filter every month and a half lots of maintenance death fluid all that crap makes diesel’s just not worth it anymore unless you own a fleet

Works well

By far the best fuel additive! Run the regular in the summer and this in the winter and I’ve noticed a substantial gain in fuel mileage!

Great stuff
