Does oil, if in original container and unopened, go bad? If so, how long does it take? Found half a case of amsoil synthetic that I forgot about, about three years old safe? | ||

mobil 1; 09/02/2008 Q) What's the Shelf Life on Opened Bottles of Mobil 1? I could not find an exact answer in the FAQs. I did read that Mobil 1 has a maximum shelf life of 5 years for un-opened containers. Is this true also for opened containers? I have a quart of Mobil 1 E... A) An 8-month-old oil, even opened, should work well in your engine. As long as the bottle is capped and kept dry, the product is safe to use for up to 5 years. Keeping it cool and dry are the key condit... Wiki; Answer: It appears from my limited research that it depends how it is stored, not too hot and not too cold it will be okay for years if it is in the original sealed container. Some companies will only guarantee it for two to five years on the shelf but others the web say that if it is shook well to remix the additives in the bottle then they haven't any problems. Don't store it any other container and don't leave open to air as it oxydizes. Opened bottles will deteriorate much quicker. Motor oil does have a shelf life. Depending on whether it is synthetic or conventional, it can be stored from any time of two - five years. I had an unopened plastic container of gear oil (SAE 80 ie thick) and over a number of years the container started to collapse, suggesting that the oil was reacting with the plastic or, more likely, that some more volatile or smaller molecular particles had passed through the container walls reducing the pressure inside. Thus I would suggest that the oil properties changed over time, probably for the worse. The shelf life of oil will, in addition to temperature, temperature change, humidity depend on the container that it is in and its make up (what kind of oil it is ) Amsoil; http://www.amsoil.com/techservicesbulletin/other/tsb%20ot-2005-11-21%20storage%20and%20handling.pdf AMSOIL Product Shelf Life Recommendations Product shelf life varies significantly depending on product design, environmental contamination, chemical contami- nation and temperature. With proper storage, most liquid lubricants can last several years. Because grease can harden or lose its oil content over time, it generally has a storage life of two years. For questions regarding shelf life, call AMSOIL Technical Services at (715) 399-TECH. Testing may be required to re-certify a product. Analysis to determine if a product is suitable for use can be performed to determine if it still meets the original manufacturing specifications. (Message edited by sleez on June 25, 2013) | ||

Oh big deal..two nails in a jar.....yawn. That's a baby food jar of water with a couple ounces of Pyroil "B" lubricant. Dad put that together in 1950! 63 years under water and NO RUST! The nails are still in concourse condition! It sat in the basement at the farm till I took possession of it in the 70's. Dad was always testing oil and grease on strips of tin cans ,nailed to a fence post to see how they held up to the elements. I would say Pyroil "B" passed the test of how long oil will last.....  | ||

If oil life is 2 years in a sealed container in climate controlled conditions, why does Mercedes Benz recommend Mobil 1 with change interval of 2 years / 10,000 miles, in supercharged engines. Seems storage is harder on oil than actual use. | ||

I think they are just trying to rotate their stock. I think new oil in a sealed plastic bottle would last pretty much forever. For instance, when I moved, I found a filthy old bottle of 20-50 that had fallen behind something about ten years prior (I think!) It was unopened so I looked it over before using and it looked flawless. I put it in along with two new bottles (same brand) and nothing weird happened. | ||

thanks for the advice i'll make sure i shake it up before entering my 1125 | ||

Ummm... I dunno if it needs to be shaken like a can of juice before your motor gets it. Kinda thinking the regular combustion cycle of the motor at idle will do it. Entropy is inescapable, but pretty dang slow when confined inside a sealed jug of motor oil. Olio, canola, grapeseed, Crisco, should go bad a lot quicker. | ||

Pour out an unshaken quart of oil and look at the bottom of the container. See all that stuff? That is additives that have settled out over a period of time and are supposed to be in the motor. Shake and pour has never failed me....  |
