expired lube oil

expired lube oil

(OP)

in our company we have a large amount of lube oil which is expired on 10/2015.
can we use this oil?

thank you

RE: expired lube oil

I assume it has not been used? Has it been tested? Is it still in spec?

Good luck,

To a ChE, the glass is always full - 1/2 air and 1/2 water.

we take a sample from the drum, and we find that the properties in the range.

it has not been tested yet.

but we don't sure that it will be in the range in the operation.

RE: expired lube oil

If you are not sure, do not use it.

Good luck,

RE: expired lube oil

But if it is a large quantity, and it has been stored in a protected area it would be worth paying to have samples tested.
It is hard to see how an oil sitting in drums would 'go bad'.

RE: expired lube oil

If the testing is not obscenely expensive, do as EdStainless suggested and you can breathe easier in the long wrong the next time you end up with a few barrels that expire on 12/2016 and you didn't see it until 06/2017 (if the testing proves it's good).

RE: expired lube oil

(OP)
yes the quantity is large (about 405 drums), and the storage condition not bad.
the sample test is free because it is done in our company.

thank you everybody

RE: expired lube oil

IF the lube oil is bad, or is used and the equipment fails, how much do yo lose? Total cost of the shutdown, the lost production, the replacement equipment, and the repair/re-installation manpower and support (cranes, tooling, admin, support costs like scaffolding and testing and balancing and startup?

If you use the oil, then replace it earlier than the standard interval: The oil is marked "Use by" 15 months ago, right? So, if the standard interval is a two-year oil lifetime, you have nine months left. If the oil has a six month lifetime, it is now 3x oil-lives old.

RE: expired lube oil

If you ask the lube oil supplier and give them some details on how these drums are currently stored, they should give you some feedback ?
