Solarent: Not to speak on behalf of Shell, but I think it's funny how a single isolated test (even done by the good folks at PQIA) and people are declaring that GTL must be being added to PYB... yeah right - I don't believe that for one second.
There could be multiple reasons for these samples to have lower NOACK's that have nothing to do with GTL stocks. If anyone thinks for a second that they would have a high concentration of an expensive synthetic base and then sell it as a conventional - whether or not Shell has a surplus of GTL - they are crazy. There is an entire market for high quality Group III base stocks sold to blenders - if they had extra they would sell it to those of us who wanted to use it to make synthetic products and make top dollar.
And those bemoaning the Nextgen result and blaming it on using rerefined stocks shows a painful lack of understanding of the process. Most re-refined stocks go through the exact same kind of processing that heavy crudes (such bitumous crude) does and they produce base stocks of the same or better quality. If I were to provide you with two samples of base oil made from virgin and rerefined feedstocks I bet there isn't anyone on this board who could tell the difference.
Well stated Sol.
As I stated in post #3243045 there are many ways to formulate a conventional oil and get those kinds of specs without GTL.
