Just because it is on the list does not mean it is OK to use.
A 30 grade oil may be a bit to thin at operating temperature.
I too must question you here. It is my understanding that any oil on 229.3 is fine for this engine.
I also notice the the viscosity range approved in 229.3 is rather narrow, that is, there are no oils such as 20W50 or 15W50 or anything even close to such think oils approved. This implies to me that 229.3 is a rather narrowly defined list specific to this and a few other engines. NOT to a wide variety of engines as your post kinda implies.
What oils on there do you think are off limits? (Asking cause I run Mobile 1 5W50 here in the south and refuse to use anything else).
