I have used this product before and it's the best fuel stabilizer out there. Now as for the seller worst service I have ever had on Amazon. I placed my order on 9/14 it arrived today 9/24 it took 10 days to get from Phoenix to North Carolina mainly because it say in Phx. for for nearly 5 days. I have received products from China in less time. I would have cancelled but I paid with credit card points and would have lost them.Bottom line pay little more with another vendor and get your order in a normal time frame.

Been using this off and on for several years, finally used up my first bottle after a decade (I know it says discard after 2 yrs, but works) Everything I have treated has been "pump fresh" after treatment even a year after. Most gasahol you get these days go bad in a matter of weeks if left untreated. this stuff certainly works!

After watching some videos on how this can bring fuel back to life, I thought I'd give it a try. Works great! Replace the PRI-G product after 2-3 years (I don't remember their recommendation) and always get non oxygenated fuel for any storage. Since then I have never had any problems with any older fuel, including leaving it in a small engine over the winter. Keeping fuel in the engine greatly simplifies any off-season preparation. Highly recommend this product!

I bought this for gasoline long term storage. I watched a video from Taryl Fixes All and it seemed to work. Pretty expensive but if it works, it’s worth it.

I haven't had a chance to determine its effectiveness, but from reviews here and elsewhere, I'm hopeful. Apparently, this stuff is extremely concentrated. 1 ounce treats 16 gallons. For those of you, like myself, 10ml will treat 5 gallons. The label is a bit confusing and lacking in how long a treatment will last. One reference says 5 years, yet another says 1 year. I've read elsewhere if gasoline is treated every two years it will keep indefinitely.... I find that one hard to believe. I guess I'll try contacting Petroleum Research to get real answers.
