M1 (10w-30) pours dark brown out of new unopened bottle of unknown age. I am only familiar with a lighter amber color for oil. Oil was kept in garage cupboard under moderate SoCal temps many years.
Can it still oxidize sealed & no sun?

I'd shake it well and pour it into my engine with confidence.

Do the oil makers put a 'date code' on oil bottles?

Zee0six Chevron Havoline does put a manufactured date on their oil containers. I had Havoline Pro DS from 2015 I just put in.

Shake and put in is correct as OneEyejack said.

The jugs will leak before the oil goes bad. laugh

I've had the worst luck with M1 jugs, but granted it was AZ clearance. Highly rotated WM stock would probably be fine.

It should have an inked or laser etched number on it that contains the date code. If laser etched it may be hard to see.

This has been my experience based on UOAs of 17 year old oil that I used.

I've used Havoline conventional dated between 1980 and 1987 in vehicles in the past without problems. Found a goldmine of the stuff in the early 2000's at a garage sale an elderly lady was having after her husband passed away. There was around a dozen 12 quart cases of the stuff, a dollar a case. I've used it mostly in older vehicles (that recommended the spec), lawn mowers and other yard implements. I have one case remaining and have no qualms about using it.
I would think that a synthetic motor oil made to more modern, stringent standards would be alright! grin Maybe for giggles I'll have to get a VOA done on a quart of my Havoline, see if any of my engines are systematically doomed. I don't fret, though.

There is a member here that had been using oil from 1974 in his Datsun.
It will be fine, perhaps just agitage it well.

Found YouTube videos showing how to read and interpret oil jug manufacture date codes even one where there is a date code on the front and it says on the back it's good for five years. So therefor my Valvoline bottle showing J1917 would mean Oct. 19 2017 manufacture date because J is the 10th letter and Oct. is the 10th month.

X2805 - looks like 2005? what is the X?
I will check some other bottles, and also post the color.
Any idea's on the dark brown color?

I will add engine ran smoother after oil change.

Don't worry about it. Shake it well, then pour it into the sump.
