Does this expire and does it require any special storage parameters (ex. between certain temperatures)?

Yes. It expires usually a year from the manufacturer date. It also has an expiration date on it. As far as storing it I would keep it at room temperature. I three 8oz bottles that I keep in the cabinet under my tank for emergencies. Like when I once did to thorough of a cleaning and caused a mini cycle. I poured half the bottle in and tank cycled in few hours so I know room temp is sufficient for storage.

Yes there is an expiration date on the bottom of the bottle. Mine expired 2 years from purchase date. Should be kept in room temperature I'd guess but doesn't need anything special in terms of storage. Just be sure to close the cap tightly.

It is not necessarily expired. There may be a "freshness" date but unless temporatures are very high or low, it will work fine.

One year according to the offer in the box. No indication what cost is afterwards or how long you have to move the "extra storage" before offer expires.

I don't know if there is an expiration. I'm not an expert. If I were you, I would use it as long as it's not separated into fluid and goo.

I found no expiration date on the package. I used the previous package approx. 2 years with no notice of degraded performance.

I have used it up & did not look at expireation date, sorry. It worked just fine, it was OEM.

I can't say that it ever occurred to me that it could expire. It's a good thing to know. Sorry

Not sure, what I do know is some vendors recommend keeping it refrigerated. I see no issues with mine up to 45 days.

I beleive that will depend on the storage conditions. If you store it in a cool dark place then it's shelf life will be longer. I stoare mine in the garage so it gets hot which shortens the shelf life. However, I think even if stored hot it should last at least 2 years.

As far as I know there is no expiration on this product. But I've normally used it within 6 months.

Yes, as others said, there is no expiration date. I simply added mine to my reserve.

I imagine it has an expiration but there is not one listed. No refrigeration necessary.

It can pass the expiration date and go rancid. I purchased 2 years ago and mine has NOT done that yet. Keep it in refrigerator to extend life of product indefinitely. Hope that helps...

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.
