Have used it in our RV since 1996. Have never had a problem with the engine. Add it with each fill-up.

I had mentioned before in a previous post that the bottle index for measurement was not adequate in small denominations for most current gallon size small lawnmower top offs etc. I found the ideal temporary solution with STABIL in the large container which has a measurement down to a 1.4 oz. . I have bought the STABIL large container and when that is empty will pour the new product therein. Eventually in competition will settle the matter.

It appears to do what suppose to, but I am only in the first season so it is hard to tell.

stored gas in 5 gallon cans for 1 -2 years without any problems. No gumming up for ethanol blends, everything continues to work, never had to drain yard equipment of gas for winter storage, just let it sit all winter start it in the spring use it all summer. Haven't needed a carb rebuild kit for any piece of equipment since I started using PRI-g on every gas can I own. Used to be a regular thing with carburator floats, bowls needles regularly getting clogged with gunk from ethanol blend gas.

Pri-G is a fantastic product and I have used it for years. I learned about it from a small engine mechanic who swore by it. It is the only product that can be mixed with OLD gasoline and makes it usable even when stored for months. Other fuel stabilizers must be mixed with fresh fuel in order to work, Pri-G works with any gasoline AND you can pour it into the tank at the end of the season and that engine will be fine months later. No more draining out the fuel or running it until it dies to get rid of this seasons fuel.

I use this to keep my emergency gas cans fresh. I add more every six months and try to run the old treated gas in my car and replenish it about every year. I've never had gas go bad with it. I like it much better than Stabil and it's actually cheaper since you use less per gallon of gas.

yes, this is THE STUFF. Put it in a old motor bike someone didn't want, now I have a motor bike. List goes on and on.

Best product on the market

This stuff works great for storage on small engines. The big test for me is an old Aries snowblower that gets run only one to two times a year at a seasonal home. I store the blower in a tractor shed with a dirt floor . It had the same gas in it for 3 years before adding more on the 4th. It always starts good. Much better results than the red stabilizer I used to use. I use it in 3 snowblowers 2 lawn tractors and all my premix gas cans.

I've been using PRI-G for many years, from before they started mandating ethanol be added to gasoline.I use it in my marine, airboat, and small engine fuels; it really is that good!It's economical too; one ounce treats 16 gallons of gasoline.

Here is the difficult thing. If you have something that is a protective product and you don't have a problem are you sure it is working? I store gas and diesel for farm equipment. Occasionally I don't use it within a year or so. While using other additives I had some difficulty putting older gas in my truck to use it up. Since swicthing to PRIG I haven't had a problem using gas as much as 18 months old. May last longer I don't know.

The best product available.

I bought this product because of its efficacy in gasoline treatment for stabilization. I can add this product to stale gas and bring it back to its original potency. It's never let me down.

Along with using boat gas this will keep gasoline usable for years.

I have been using Pri-G for years to keep my fuel going bad it works.

Way better than Sta-Bil

Worked on year old ethanol fuel in my Motorhome. Had to pull the fuel filter but it started after that

Kept the gas in my Motorhome fresh for over a year.

the product is great but seems to leak, the two times i have bought it from a online source.i used it for a good year now.if you do the math PRI-G is actually cheaper than the other stuff and every one i know swears by this stuff.

Years ago, I went looking for PRI-G after it was recommended by survival experts and found it here in a big 32 oz bottle. I've ordered it several times.I live in a rural area and have a tank that stores 300 gallons of gasoline. I use it as required and then top up with gas cans filled in town. It doesn't take very much of this additive to condition the gasoline. Just follow the directions on the bottle that comes with a handy built-in measuring cup. I've used this product for several years now. Even if gas is left in the tank after a year, I can continue to make it good by adding more PRI-G.The challenge storing gasoline, especially these days with ethanol in it that deteriorates over time, is keeping it good. The worst thing for most small engines, and your vehicles, is bad gas. PRI-G is the very best way I've found to condition the gas for long-term storage -- far better than those cheap brands of so-called gasoline conditioner you can find in many a big-box store. A small engine mechanic told me that he's seen the inside of thousands of fuel tanks, and much of them had jelly lying in the bottom -- those cheap stabilizers. Never use those, he told me.PRI-G is the answer to storing gasoline, especially when doing it for months and even years, and I've proven it works.Highly recommended.
