priFuel Stabilizer - Gasoline, 16 Ounce- Fuel Economy Booster

EDIT (Nov 10, 2017):This stuff seems to work well I had about 12 gals of gas on hand from 2 years ago that I have been treating once a year with this stuff than Halloween 2017 we lost power for 4 days. I ended up burning ALL the old fuel with no problems and you can bet that I treated all the new fuel I got that I thought might sit for a while. The only equipment (besides my vehicles) that take regular gas now is weed whacker and pressure washer. Both are only used a couple times a year so I wasn't going through my old fuel stock very quickly but with this stuff that wasn't a problem! I still have not tried to revive old gas though. If I do try it than I will update the review for sure!Original Review (Nov 3, 2015):The verdict is still out since I just switched to Pri-G from Stabil this fall season. If it does what it says then color me impressed. I store quite a bit of fuel on hand for the genie (~25 gal). I figure if we lose power again for 4 days then I have enough fuel to get us through it (start and stop genie as needed of course). I almost want to rotate one full canister (2.5 gal) out and treat it with Pri-G once a year and see how the fuel looks / smells / works in 3 years.

I have a Honda lawn mower and have never treated the gas when I store it for the winter. Last spring when I tried to start the mower I pulled on the rope at least 30 times. When it finally started it smoked and sputtered until I dumped the gas out and put new gas in. Even still, it ran like crap all day and every time I engaged the clutch it would die or almost die before it revved up. This year after reading so many reviews I went out yesterday and put 15 drops of Pri-G in a full tank of mower gas that had sat all winter long. Today I went out and the crazy thing started after 2 pulls on the starter rope! Not only did it start it didn't blow any smoke at all. In fact it sat there and idled with only a small hesitation which went away after a minute! The unbelievable thing is it ran like I had just dumped premium gas in it! To all of those jokers that don't believe that Pri-G can restore gas to refinery fresh conditions you obviously haven't tried it! I am as skeptical as they come and it made a believer out of me. I am sure Pri-G is capable of keeping gas in great condition for a few years. There is no doubt it rejuvenated the gas in my lawn mower. Not only did I not have to dump the gas out and put fresh in, my old gas is as good as the day it came out of the pump!

We have used this fuel stabilizer product for years in gas tank fillups for all of our shed power toys and lawn tractor. We live in New England, so our tools are stored for the winter, including the gasoline inside of them. Come spring, we have never encountered any problems with gummed-up carburetors or gas-lines since starting to use this product. PRI-G is better than STA-BIL, which we used to use, because it offers a concentrated, more efficient fuel stabilizer and treatment. Both products are available in 16-oz bottles, but the PRI-G treats 6.4 times more gallons than the STA-BIL brand in that amount. PRI-G costs more and lasts longer because it is highly concentrated - but it is worth every penny. As per the directions, we use only a quarter-ounce of PRI-G every time we fill our tank with 4 gallons of gas, and the product lasts forever. We have every power tool imaginable and need frequent refills of gasoline, especially for the John Deere lawn tractor mower. Ordered our first 16-oz bottle of PRI-G in July 2014 here on Amazon, and just ordered the second one now, April-2018. That's why I'm here and thought I would add my two cents.

I drained 10 gallons of stale gasoline from a classic motorhome I purchased to restore.The gas was nasty and yellow and I has no way to dispose of it (without local authorities citing me)I was told I had to carry the stale gas to a "environmentally safe hazardous waste dispose site" and I had to fill out paper and pay a FEE to dispose of it.GIVE ME A BREAK! This is old gasoline not agent orange!!I actually never heard of this product and the only fuel stabilizer I knew of was Sta-bil. From experience, it is not really that great only good for a year.The motorhome has to go into a storage lot and I wanted to keep the gas from getting weak (alcohol added to gasoline accelerates the breakdown of gas to goo that will clog filters and gum up fuel systems. Damn you EPA!) So after some reading I ordered PRI-G. I added some to the fuel in the motor home and for kicks I add it to 6 gallons of stale gas had. I filled the mower up with it and it pretty well considering I don't' think a lit match would ignite the gas before. You could smell that the gas was full of water and very poor.The product does as advertised so I highly recommend it!

Have been using fuel stabilizer's for many years and OK results, however, when I finally switched to PRI-G, I was very pleasantly surprised to see my fuel consumption was less, which added an additional 2 MPG. Doesn't sound like much until you start multiplying that by the number of gallons you buy. Yes, eventually it will pay for itself. 1 oz. will treat 16 gallons. On first use you add enough to treat the entire tank, then add only to the amount of fuel you put in after initial use. Normally I will fuel up around half a tank, and for us that's around 10 to 12 gallons, so I add 3/4 oz. Did I mention there is a guage built right into the spout? It has 1/2 oz. and 1 oz. markings so that makes it super easy to use. If you buy this product from any place but Amazon, you'll pay more, so this is the place to get it.On our last camping trip, we actually got 13.6 MPG from our Toyota Tundra pulling a 28' RV. We've always gotten less mileage with other brands so we're completely sold on PRI-D. You can use this on ANY gas engine, or buy the PRI-D for a diesel engine!

Too early to tell yet but a little sure goes a long way compared to other procucts.

Shipped fast. Seems to work good.
