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?

Nice. My stash is running low and even Walmart super tech is expensive now.

Quote from eng33 :
$3/qt, is that a good deal these days? I usually look for closer to around $1/qt. My 3yr free oil changes is going to come to and end soon on my car so it's been a while since I've purchased oil. I guess everything's more expensive these days.
I haven't seen $1 per quart on synthetic ever.

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.

I'm thinking about switching to Kirkland from all the great reports I've seen. I have a 5 quart jug of Mobil 1 0w-20 that I need an additional 3 quarts for, and rather than mix with this, I think I'll just get this set next week and store the Mobil 1. I can't get another single 5 quart jug of Mobil 1 for less than $31 with tax at Walmart, so it may be time to switch over.

Probably 50 cents per quart 30 years ago.

This is great... except I was planning on doing an oil change this weekend - kinda need it done before the 31st.

Hmmm... now I have to decide if the Slickdealer in me is willing to wait and book up my 30th like that.
Buy it…Costco will typically issue a price adjustment for products purchased within 2 weeks of a new ad.
