I found $1/quart on mobile 1 synthetic one time about two years ago it was big 15q bags on clearance
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.
They were that in autozone a while back, but yeah only time I'd seen that.
