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

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

This stuff is awesome!

I am not sure that I noticed any difference. I bought it because I did not want to chance my diesel gelling up.

No problem with water in fuel or winter starts in Kubota tractor! Great product! Highly recommended Best additive I’ve found!

A popular product at a good price. Unfortunately, it didn’t survive the shipping process (second time this week a liquid wasn’t adequately sealed). Being a petroleum-based product, the soaked box left an offensive odor on my hands and in the house. There was still enough in the bottle for my immediate need; but not a satisfactory purchase.
