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

I have had no issues with winter time running of diesel engines. Not sure if it does what all it claims, but I have no complaints and seems to do the trick. I had used PS and think it is a great product, but this seems to winterize just as well and should have other benefits along with the winterizer.

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

No leaks, well sealed. Shipped promptly, easy measurement reference on the bottle. I do believe there has been a small mileage increase. I will edit after the bottle is fully used.

My truck hasn’t gelled up this winter works amazing

This stuff is awesome!

Works great! A good value.

Easy to measure and the pour spout is long enough so you don't spill before getting into the tank

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
