I always leave a quart or two in the trunk for emergencies. Currently, I have one sealed (foil unbroken) and one unsealed bottle of Castrol 0w30 full synthetic. Are they still good to use on the next change? They've been there for probably 6-10 months in temperatures between about +30C and -30C.

Thanks. And I just realized... the oil sitting in the sump will have gotten just as cold (or hot), and it's just fine
Although, it's gonna be dumped and going in on a clean change.
What about an oil filter, still shrink-wrapped?

As long as it's not rusty, I would use it. Likely looks better than a couple of the ancient AAP Total Grip filters I've used on the GMC 6.2 in my sig.
At 6 months... its brand new oil in my books..
at 6 years... I'd still use it...
My last OCI, I used some 10 year old Amzoil XL in my 02 TL..

Good to go.
Lets see ...the fermenting dinosaur carcasses sat in the ground a hundred million years until they turned in to crude oil. ...Will it go bad in my trunk? ....hmmmm.
I know its not really dinosaurs but it sounds funnier that way.
I heard they found some crystallized honey in a tomb in mideast and It was still good.

The diff oil in my 67 Camaro survivor was original and 45 years old at the time I drained it to cosmetically refurbish the rear axle assy. I think it was still doing a fine job at that point.

The oil will be fine in your trunk or in your garage/shed/basement, open or unopened.
Just think, oil sits in the crankcase of an engine for sometimes a year or more in the vehicles of many. Starting up/shutting down, winter/summer, heating up/cooling down, revving/idling.

Somewhere on this site from years back is a UOA of oil that sat in the crankcase of a tractor for 30 years stored in a barn (a dry climate area). It was suitable for use.... even though the analysis showed a modern oil would be a MUCH better choice. Also, go to the Blackstone site and they have done oil analysis on unopened cans of oil from 20, 30 and 40 years back and they test fine (by the standards of their day... I wouldn't use a 30 year old oil fomulation because what we have now is so much better). The only danger is that some additives may settle over a long period but a good bottle shake before opening deals with that. Some common sense needs to be applied here too; an unopened can/bottle is one thing, in the crankcase is something else.
FWIW, I just used the last of some 10 year old Royal Purple oil.
