Is SAE motor oil still good several years after purchase?

I found some old Castrol SAE motor oil in the basement that never got used, one bottle is unopened the other is about half full. These were purchased at least 6 years ago, still usable or toss them?

it does have a shelf life but it does vary have read up to 5 years I probably would use it myself and not give it a second thought in a vehicle or engine that used oil, really up to you to decide what to do with it.

I wouldn't drink it but it's probably OK for the lawnmower.

FWIW...if unopened and stored in a cool dark place, then use it as long a sit meets the specs of the vehicle or appliance.

I agree with Norm, as long as the quart is un opened and meets the specs of whatever you intend to use it in there shouldn't be any issues no matter how long it's set. I'd just use the opened quart for lubrication [oil can] or add it to several qts of fresh oil.
