E-Zoil H15-16 16 oz. Bottle of of H.O.T. Shot (Hot Shot) Heating Oil Treatment.

Oil burner is running like a champ, used to have issues all the time. best kept secret, buy three for the winter every year!

Upon using I have noticed that my oil burner runs much smoother and quieter. I will be using this with each oil fill.

As with numerous products like this, it's not easy to review since it doesn't work all at once and it takes a while before you even know if it is working at all. Easy to add to the oil tank for sure and I'll post an update once I find out if it really is removing sludge or not. Won't know that for at least a few months... tbd...

Clean fuel.I would not recommend the company we bought it from. They charged twice the amount you can purchase it for. (We thought it was for 2 bottles at that price). When we went to send it back they wanted to charge us $15.99. Half of what we paid.

As advertised. No more sludge no more water. Oil burner is happy and so am i.

Works great.

First time I've used it. Time will tell if it is effective as adverrtised

We had our Boiler Man out to unfreeze our Boiler 2 years in a row. He used this stuff. This year he told us to startadding a 1/2 bottle to our tank at every fill up of fuel oil, to prevent our oil from jelling at the nozzle. This is cheaper than paying the boiler guy, that's for sure.
