Yea, my point however, was look at where you are posting.
Of all the places where the smallest hairs related to oil are to be split, this is the place.
Perhaps if you posted in some consumerreports forum, then you'd have a choir of consensus that it doesn't matter as long as it meets the spec.
BITOG is the specific area where the differences are laid out.
So even if it maybe true, it's a bad analogy to use to try to make your point... for this audience.
Here I'll make another analogy about your analogy.
It's like saying all cellphones are the same, they all make calls, they all surf the web; they all play music. If you're posting in a generic forum maybe that's a fine analogy to make about commodized items.
But if you were posting in an android developer forum they'll say that's a inaccurate analogy to use to push that point, as all they talk about is the differences and fine details.
