I agree completely (except its not my bottle) and ironically why I posted in the HEDO Diesel oil section what I did days before your post. (see link below and read first page)
The thing is, if you want a 15 or 20/50 CH4+ or better HEDO oil in the USA you have to settle and trust a name brand company to be telling the truth as far as the "claim" of what it meets.
I only know of 2 oils in the 15 or 20/50 HEDO range and both of them "claim" to meet API classification but I do not see the donut.
Yet over seas 15 and 20/50 HEDOs are easy to find. Maybe there is a reason for this, I dont know.
Those two oils that I know of are Amsoil and Mystic. Amsoil made by Amsoil and Mystik made by Citgo, two name brands that sell certified oils.
So its blind faith, much the same as maybe 50% of motorcycle oils on the market that carry zero certifications, only claims.
For me personally I trust the Citgo Mystik brand way more then a motorcycle rating simply because the Mystik is used and produced with a claimed c rating. They would be blowing up equipment far more expensive then a cheap motorcycle, never mind ruining their brand which is acknowledged in the agriculture industry.
Its whatever one is comfortable with, me, I trust Citgo being, even more so, with someone in the HEDO sction called into my statement of exactly what you posted, only I posted first!
He produced a paper saying the 15/50 Citgo does/is certified as a CH4/CI oil.
But to each his own, if someone is not comfortable using an oil such as this,
I agree with you COMPLETELY, by all means, dont use it! For me, I dont see much choice unless someone can tell me where to buy 50 weight CH4+ or certified oil in the USA!
I prefer the donut but gave up looking and why I ran so many UOAs.
I trust Citgo/Mystik a little bit because their mainstream oils are all certified, but a 50 weight HEDO in the USA with a CH4/CI rating is almost uncalled for in modern diesel engines, except in heavy industry and farm equipment which is supposed to be the reason Citgo produces it.
Anyway, click here to see what I wrote before you did!
