SUPER CONCENTRATED PRI-G COMPLETE GASOLINE TREATMENT for all engine types IDEAL for E-10 GASOLINE

There is absolutely no better product for either gasoline or diesel fuel treatment or remediation on the market that I have found. It just works better than anything else. I know for a fact that fuel that I have stabilized for over 3 years that has been refreshed with an additional dose of this product runs better and cleaner and carbureted power equipment than fresh non-ethanol fuel without fuel stabilizer. I have the carburetor bowls and the spark plugs and the mechanical repair experience to prove it. This is without exception my favorite fuel additive. I buy this and use it religiously, because it just works so well. It has never let me down and over 15 years of consistent use. Other products have. This size bottle is going to be your best value for the money, and I always recommend buying it in much larger quantities than you think you'll ever need or use, because you will need it. The only downside to this bottle, is that it is somewhat easy to over treat and waste product. Fortunately, there is absolutely no issue with over treating at all.

Been using this PRI-G, along with the Red and Blue stuff of a different brand of fuel STA-BILizer for 15+ years. I dose up my fuel cans before filling them with ethanol-free gas to let the gas pump mix it all together really well. Then I seal the fuel cans and pop them into my shed. Longest I've had fuel stored prior to use was a lil over 4 years. Fuel burned great in my generators and my newer vehicle. Can't speak to the rejuvenation of old untreated gas, as I treat mine before storage, but it keeps my gas peppy for years on end. Not sure what's in it, but it seems to work well! Told a guy about it at the gas station tonight. He said he's interested...and as I drove off, I realized I never left a review for this product. So here's my review. Would buy again. Would recommend to others. Can only give 5 stars, otherwise would give more. It's not magic - it won't un-gum a carb, but it'll keep your gas fresh and peppy for years on end in storage, if you store it right.

This stuff is a lifesaver! I used to have problems with my lawnmower after storing it for any length of time, but not anymore. A little bit of this in the fuel can before adding it to the mower, weedeater, or leaf blower keeps it fresh and prevents gumming. Now my yard equipment starts right up every time 1st or second pull. I highly recommend this fuel stabilizer to anyone who wants to avoid engine trouble. It's a great price for how many gallons it can treat and it'll save you a lot of money in the long run. I don't know if there is a shelf life on the product itself, but I've been using this stuff for over a year and haven't had any issues. And it's now on Amazon! Only thing to add - look if you have EXTREMELY old fuel WITH a lot of water in it then you'd be better off draining the tank. Will this stuff work? Possibly, but not on something like a weedeater or chainsaw etc. So my advice is to treat the fuel before you put it in your machine and store the leftover fuel in a relatively stable temperature variation. They still make metal fuel cans and those are best for long term storage with this added.

I was out of the country for 6 months and my car was going to sit so I actually overdid it with the PriG and probably put in 4 times as much as was required for a 13 gallon tank. It was normal up to 10% Ethanol gas. I did make sure the tank was full before adding the PriG because a half empty tank of gas will go bad faster than a full tank. Still I'm impressed.

This is the best value for your money when it comes to fuel treatment. The ease of use with the build in measuring cup. Make adding the correct size to fuel. The treatment is very compatibility with 2 stroke and 4 strokes. The versatility of the treatment makes this treatment to choice every time. I've used this treatment for years and all my fuels have never had an issue. Keeps the gas nice and fresh. I've had fuel close to 2 years old and no issues with lawn mowers or gas edgers. I'll never use another treatment again. I always keep extra laying around.

So far so good. From what I can tell, this product does work and extends the life of the gas.

We looked everywhere locally for this product and could not find it. Had read reviews by people who had used it in motorhomes and other vehicles that are not used on a regular basis. That was what we needed. So far, it is living up to the praises.

I've had a few engines in my life and I always had fuel problems before I started using PRI products. Some of those problems were extremely expensive to solve - replacing high-pressure fuel pumps, cleaning tanks, sensors, new filtration systems... low quality fuel will destroy whatever it touches. Since I started using PRI products (PRI-D for diesel and PRI-G for gasoline) I have not had a single fuel issue. This stuff is worth it's weight in gold. You can look up tests by PRI and others, but there is a reason why industrial customers buy this stuff in 55-gallon barrels. I have used gasoline that has sat for over a year with absolutely no issues and would have total confidence in using it in even older gasoline. PRI themselves claims you can use it on 10-13 year old fuel. Now - obviously people love this stuff, but there's still a bit of fiction out there about what it can do. What's fact and what's fiction? Fact: it has an infinite shelf life when sealed, restores degraded fuels, is excellent at preventing biofouling, carbon deposits in the engine, and improves emissions. Over-dosing is not harmful, although should be avoided long term. What is fiction? For starters, it's not an octane booster: straight from PRI, "PRI-G is not an Octane booster. PRI-G will only increase Octane marginally. PRI-G will not increase combustion efficiency." The claims of increasing mileage and not increasing combustion efficiency may sound contradictory, but it can still save gas in several ways - for example, cleaning engine components and preventing phase separation of water and fuel in ethanol-blended fuel, preventing knock and pre-ignition, lubricating the engine to reduce friction, improving vaporization of fuel etc. Also fiction is that you have to mix it in the tank: PRI themselves claim that simply adding it before adding your fuel is enough.
