The point boxster is that many recommendations that are in the big thread only take 1/2 the factors into play. And are therefore invalid. I personally like bp and vr1... But maybe the bp car gets changed every 4k miles and maybe the castrol car only got changed every 8k miles. So maybe more frequent changes are the deciding factor... Not the brand. I read every page of that thread and none of the gurus resolve this issue. It's all just preference.
I think the op was just point out the variability in opinion and the lack of any real evidence based statements. My approach is to just choose an oil with at least 1200 ppm. There are 20 on the market. And not get into the syn vs Dino, brand a vs brand b because most of the arguments are bs.
