How long will a partially filled bottle of sta-bil last sitting on a shelf in a outside storage shed?

Given the two responses already provided, I would tend to suggest those are accurate. I suspect potential freezing, or extreme heat would shorten shelf life, but do not see any 'expiration' date on the two in my shop. We tend to go through fuel both 2 and 4 cycle needs well within the 12 month 'maximum storage' for fuel with the 20 gallon packaging, so it is something of a moot point for us regarding shelf life of open stabilizer. Between chain saws, blowers, weedeaters, chippers, and generator(s), 20 gallons on the farm only lasts a few months at best, depending on power outages.

I really don't know how long it's supposed to last but I've had open bottles of it sitting for at least two sometimes three seasons and it didn't seem to effect it at all.

I'm not an expert but I have had a partially opened bottle for a year and it didn't seem to lose it's potency when it was used.

The shelf life of this Sta-Bil Fuel Stabilizer (32 oz.) is 2 years after the bottle has been opened, provided it has been tightly capped and stored in a cool, dry place.

I replace mine about once every 1-1/2 years. I don't think it has an expiration. If it did, they would make a Sta-Bil stabilizer product.

I've used the product after six months with no issue. The whole bottle isn't meant to be used in one sitting so it has to have a decent shelf life.

The structure should be good for a couple of days. water temp shouldn't make a difference. Check with the manufacturer on storing in the fridge.

Each bottle usually last 2 years if you put it in a dry and cool cabinet shelf (every bottle has labeled "best used by" dates). The power tends to harden if you let it sit too long or stored in high humidity environment. Take it 2-3 times a day on a empty stomach (before meals) and a 10.6 oz (300g) bottle will only last 30 - 45 days. Caution: avoid moisture at all time. Keep it as dry as possible. Hope this helped.

Average 20-25 years. Cooler temperature storage will extend shelf life. 55-60 degree basement storage will give it 30 years

There is a lot number on most bottles, example LOT 2806EL will usually show or be valid until 04/2013. I have have gathered more info that shows if this product is kept in an area that does not exceed 70 degrees or below 35 degrees, it will last until 10/2013. I am not a prof. on this I simply look into all conditions and go by what I have found to be true for me. If any of your supplement is cloudy or dark I would not use it and return it. Again I am not a prof. I have used this product for 20 years and this is what I have found to be true. I hope this helps.

If unopened and kept in dark area under 77 degrees, about 1.5 years. If opened and stored in the same environment, about 4-6 months. In the summer, I keep mine in the refrigerator. Above 77 degrees it will liquify, which is okay but I like to keep mine solid with a cooler temperature.

Just ball parking, I would say the bottle lasts about two months using one dropperful in a liquid a day.

Because of the cool way the bottle works this product can last quite a while. 20 to 30 days, easily.

I'm sorry, I bought this a long time ago. I don't remember the shelf life. It was well sealed, so I doubt additional sealing would help.

Same here. I used some at Christmas, and refrigerated the remaining container. Still fine. Based on similar products, as long as you keep it sealed and refrigerated after opening, it will last many months

DEF has a shelf life that averages from 1-2 years when stored properly (40-80 degrees optimum) It can expire quicker if not stored properly & ultimately throw "poor DEF quality" codes on your DIC. The container should have a batch date on the box/container, you can base how fresh it is on how well you store it. For example: if you store it in your laundry room closet and temps in your home are typical: 2 years without it going bad. If you leave it outside: 4-8 months. If you store it in your garage depending on the temps that fluctuate: 12-16 months.

My bottle has no expiration date, but I keep it in a place where it is not exposed to direct light or drastic temperature changes.

Like the other poster said, my bottle was in the fridge for at least a year before I started using it, and I had already opened it. It was fine. So long as you keep it refrigerated it will last a very long time. I am guessing the acidity level and the fact that it is concentrated, is what helps keep this fresh.

I don't currently have a bottle, but I'd assume it'd be good for at least 1-2 years before the shelf date, then likely a few months after.

I think it depends on your location. If your location has a warm climate you shoud best keep it refrigerated, and the same if you will not be using the whole contents of the bottle for a long period of time. Taken from Wolfcreekranch: "Vibactra Plus has a shelf life of 4 years (longer if kept in a cool dark place)."
