Well, I give SOPUS the benefit of the doubt on their product quality. I'm not giving them the benefit of the doubt on screwing up their PDS, though.
I simply can't see Formula Shell Synthetic 5w30 having a pour point of -36 C, for what pour point is worth. RP's 15w40 has a pour point of around -42 C. While RP might be using some expensive base stocks, that still doesn't account for the lousy data on the Formula Shell Synthetic PDS. They simply must have copied the conventional oil data to the synthetic oil sheet. I simply cannot see a company's synthetic offering having the exact same specs as their conventional.
SOPUS needs to smarten up. If I want generic specs, I'll just refer to SAE grade specifications or, better yet, I'll buy a brand or from a company that at least attempts to publish believable numbers.
