It's all made by Warren Distribution. They make Kirkland, Super Tech, Amazon, and many other private label brands. It's good stuff.

Why would you ever need to do an emergency oil change?

Hey, do you mind posting the link to the reports? I have been using semi synthetic for years on my equinox and altima, but just got rid of my vehicles and upgraded to a BMW X5 PHEV. I am trying to figure out what oil I am planning to use in this, will be 0W20 but not sure what brand would be best, thanks!
Here are some of the findings I've come across:

Yep šŸ‘ 2013, 2014, 2015. Then they went to $2/qt during their EOY clearance.
Yeah and then submit for manufacturer rebates equals free oil.
I still have many gallons of mobil 1 and rotella gas truck that I got nearly free after rebate.

You literally typed what you should have typed into Google lol

"about 7-8 years
Most conventional oil brands will have a shelf life of about 5 years. Synthetic oil and synthetic blend oil will last about 7-8 years, and maybe even longer. If you cannot find the expiry date, make sure you use up any half-opened or unopened motor oil bottles within 2-5 years of the manufacturing date."

Quote from gathermewool :
Edit: Tyman corrected me later. This is indeed the older version of Dexos 1 (Dexos 1 gen 2). This is NOT Dexos 2 gen 2.

The 0W-20 and 5W-30 appear to be Dexos 2 Gen 2. I haven't looked up whether D2G2 has been tested to mitigate low-speed pre-initiation (LSPI), common in some US direct-injection engines, especially turbos (DIT).

I personally just changed the oil in my turbo Subie (FA20DIT) with Kirkland Signature 5W-30 Dexos 1 (ONE) Gen 3, which IS tested to mitigate LSPI.

When I researched this several years ago, the Dexos 2 (not gen 2) was spec'd by GM for their small turbos, but then they changed it to Dexos 1 due to LSPI. I would personally stick with D1G3 if you have a small turbo engine with direct injection. If you don't have direct injection, then D2G2 will likely be more robust.
Standing in front of the oils in my local store and 0w-20 and 5w-30 are advertised as dexos 1 gm approved gen 3 but the 5w-20 has no dexos labeling at all.

All 3 are API service SP- Resource conserving rated though.

I remember when this was $20 just a couple of years ago. I guess those were covid prices.

Best I've seen is the Mobil 1 $12 rebate. Currently $27 at Walmart, so ~$3/qt after tax.
This is almost as good of a deal, without having to deal with a mail-in rebate.
