I don’t see the big deal on date codes. Just dumped a jug from 2018 into the backup 09’ Focus. No foaming or anything. It just works.

- Start date
The oldest of the jugs I got are at least 5 years newer than one of the vehicles it will go in and 12-14 years newer than the other 2.
The 3 I got from my store are from 2022. August if I recall correctly.
I hit another store closing down road 11 miles from me. Snagged 7 jugs of delo 5w40 at $4 with the big discount.
I don't think I ever poured any in a glass of any versions. Was that shaken up first for the settling?
Is it something we should return or donate?
It was old. I am not a chemist, but I think once stuff falls out of suspension, shaking it up again does not reconstitute the blend. It is not Iced tea.
Shaking it up does not, but it puts it back into temporary suspension and operating heat puts it back into solution. Valvoline noted this at one time.
By heat, what do you mean? Is engine heat adequate?
Would the oil in my picture re constitute?
I suppose all solutions are always "on their way out", just like the adage, "dying from the moment of birth"
That's what Valvoline said. That's all I know.
Do you still have it in the glass? Maybe some low heat on the stove and stir? We'd all probably like to know, at least I would.
I've used many older bottles of stuff over time. About the most I did was shake it up to suspend any potentially settled stuff and in the motor it went.
No I returned it.
I did miss a good opportunity though. I could have kept one gallon, and did some experiments, and sent a two samples and posted them for the experts to see here on BITOG.
Oh well.
And I suppose after that process, it was good? That would be cool. Thanks for the reply.
How can you be sure that's solids / additive falling out and not air entrapment? I still don't know what I'm looking at in that photo; I've never seen motor oil poured into glass mug. Can you be certain that brand new oil poured in a glass mug won't look that way?
well, the bottle had a sludgy goo on the bottom. checked with a kabob stick.
i used a milk frother to foam the oil, that picture was long after the mixing.
i am no expert.
Could be bad packaging, who knows.
Never tried that with motor oil, I don't think any have been tested against milk frothers. Did the wife approve?
Me either. I'll comfortably run the 7 gallons I just received in at least two of my vehicles; I'll run a UOA on at least one OCI. If I see anything alarming at the bottom of the bottle (I don't own a milk frother for that test) I'll be sure to post here.
The three bottles that are presently in my 6.7 CTD were dated 2024 and the bottom of the bottles came clean on the pour.
I sold all the bottles that were 2017-2023 so I can't help.
help with what?
Oh my god; I guess the engine in our kia will grenade with the delo from 19’ I put in it.
I see no issue with oil from 2017-2019 etc. engine heat will help it work fine.
