expired lube oil expired lube oil elowami (Chemical) (OP) 27 Nov 16 10:37 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 Latexman (Chemical) 27 Nov 16 12:41 I assume it has not been used? Has it been tested? Is it still in spec? Good luck, Latexman To a ChE, the glass is always full - 1/2 air and 1/2 water. RE: expired lube oil elowami (Chemical) (OP) 28 Nov 16 07:26 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 Latexman (Chemical) 28 Nov 16 12:17 If you are not sure, do not use it. Good luck, Latexman To a ChE, the glass is always full - 1/2 air and 1/2 water. RE: expired lube oil EdStainless (Materials) 28 Nov 16 14:17 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'. = = = = = = = = = = = = = = = = = = = = P.E. Metallurgy, Plymouth Tube RE: expired lube oil jari001 (Chemical) 28 Nov 16 14:42 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 elowami (Chemical) (OP) 29 Nov 16 07:59 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 racookpe1978 (Nuclear) 4 Dec 16 01:41 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 georgeverghese (Chemical) 4 Dec 16 03:40 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 ?
