What is the shelf life of this product if unopened/still sealed?

Royal Purple does not list the shelf life so a call to them should be made. Mobil 1 has a shelf life of 5 years. Basically the oil does not go bad rather the additives may separate from the oil.

Richard, I don't know about a shelf life. This stuff is so good that it is never around here long enough to know. It sure is an outstanding product.

I purchased a large quantity of this item last April 2012 and there is no expiration date. I would guess the shelf life lasts for years in sealed packets.

According to manufacturer, expiration date is generally three years after production. So long as you limit the product's unnecessary exposure to air and moisture (and follow manufacturer's recommendations that product be stored in "dry, cool and dark" location), it should, presumably, stay fresh in its resealable bag for the amount of time it takes you to use it all up.

I haven't owned it that long, about 6 months. But before purchasing, I researched it and most say it has a shelf life of about 10 years if stored properly. Don't break the seal and keep in a dark place, fairly cool and a pretty steady temperature. I repackaged mine in mylar bags with oxygen absorbers which greatly increases shelf life for most dried products. Hope this helps.

Unopened, it will stay for 15 years. Opened, the website says it will stay viable for up to 12 months.

The last shipment I received had a shelf life of 8 months on the box. It however most likely varies with each shipment. hope that helps. 11/14/2013

It has been packed with an oxygen absorber so it should have at least a five year shelf life if unopened. After opening it should have 9 months to a year.

Not sure about the shelf life, but I've had mine up to two years if stored in a cool dry place .. maybe even longer, asthey are sealed in plastic....

Unopened in fridge or freezer is basically forever but realistically 3 years. Once opened, kept on counter, always using a clean spoon, and stored "not" next to stove... About a year.

Depending on storage conditions: temperature & moisture exposure; I would think that this product would keep almost indefinitely even after opening because there isn't anything to break down without exposure to other things. I recently found a misplaced opened package (with ziplock closed) and it seemed in perfect condition and this was over a year.

Not sure how long it lasts but I think, unopened, it would have a long shelf life. I bought a case about 10 months ago and still have 4 unopened. I really can not see how they would turn bad. Most condiments and spices seem to last for a couple of years.

The product is sealed...it should last for quite some time [perhaps a year] if kept cool...a Korean 'grandma' showed me how to preserve it after opening...pour sesame oil on it and refrigerate it...the oil keeps it from drying out and adds a unique 'Korean' taste to it.

As a general rule, the shelf life is 9-12 months. All depends on how the product was stored in your home (a cool dry place). Hope this helps to answer your question.
