Any chance at Warren 0w30?

The Kirkland 5w30 has Been holding up well for 7-10k intervals in my Tacoma. Of course it’s Texas and I run 10k In 6 months so it’s an easy life. I wouldn’t worry about 0w30 unless you really need the cold weather performance
 
I service a few vehicles with 150K to 230K. They spec 5w30. A couple go through a little oil.
I woluld like to see a Kirkland 10w30 for these cars. We don't worry much about sub zero temps around here...
The 5w30 seems to do the job though...
 
In Canada, at least, WM used to market a ‘Tech 2000’ 0W-30 many years ago (late 1990’s). It was re-labeled Petro-Canada 0W-30, and it was not a big seller at all.
It still wouldn’t be a big seller.
