Great product easy to use great value compared to similar products
Purchased to maintain stored fuel when prices are high.
I purely bought this product for the bottle pourer as it leaves no mess compared to the Diesel Power Chemtech bottle.
Great for stored mower fuel that may sit for a year before being used
Keeps my fuel fresh so it's still good for my car and mower
Not the product's fault, however, as I went to pour it into my boat's fuel filler, when I removed the cap I observed that the foil sealer had been removed, and some product was missing.Suspect that product had been returned to store by another customer.On reflection, I probably should not have used it, and returned it to the store, however I was a long way from where I purchased it, and I was anxious to get the stabiliser into my fuel.
Too soon to tell if it meets its stated performance
If you have any fuel that you are storing for a length of time throw a splash of this into the drum too and it will keep the fuel Petrol/diesel in tiptop condition.
