PQIA tested it a few months ago. I'd post a link but that's very difficult from my phone. The ST 15w40 looked fantastic in their tests.
Here is the 2013 Supertech 15w40 PQIA test (PQIA Link)
It's the API CJ-4/SM version with a bit over 1200 ppm Zinc.
If they have updated the formula to CK-4 then this zinc level may have changed.

Good work mate.
Year: 2016
Product: SuperTech
Viscosity Grade: SAE 15W-40
Labeling: API CJ-4/SN
Zinc: 1298 ppm
TBN: 9.58
Noack: 11.3%
Ca = 1249 ppm
Mg = 858 ppm
Mo = 47 ppm
KV100 = 14.98 cSt
Looks like a good oil for old school engines without roller cams.
Has SuperTech been updated to CK-4 yet ?

Thanks for posting the link. I'm about to put 5 gallons of this in a 1959 Austin Western road grader with an International gas starting diesel this weekend.

Love those gas start/diesel run IH motors. Nearly indestructible and they make power

This one is the largest 4 cylinder IH of this era that I've ever worked on UD14A I believe is the designation. 460 cubic inch 4 cylinder. The grader was owned by the country road commission and there is no telling how many hours are on it. Just for fun we're going to do a UOA after we run it for the season on the ST 15w40. It's getting all new fuel and oil filters as a part of the service this spring.
I also love these engines, about 5 years ago we were in a pinch and needed the grader, it was -17F and it hadn't been started in 4 months. With nothing but a group 31 car battery it was up and running, pretty amazing for a 1959 diesel engine!
