Not sure if this is the correct forum to ask this question.
Both oils being full synthetic.
Does 0W20 full synthetic use a higher base stock oil(and other unseen additives) compared to a 5W20 full synthetic oil?
I do see differences in same brands(between the 2 grades) but more closeness from brand to brand.
I ask because when I look at many oils on the PQIA and make comparison between the two grades(full syn), I see some that are further apart from one another and others in which are very close. e.g., starting TBN, cST @ 40 degs F & 100 degs F and multiples of other measurements.
In other words, I could use one brand of 5W20 full syn that is close in its measured areas that is right on top of another brands 0W20 full syn.
