Have been using Penrite Fuel Stabiliser now for several years and have found it to be extremely effective in helping to keep fuels fresh both two stroke and four stroke and helping especially with cold starts early in the morning.

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.
