Hi All
Just checked the MSDS on American Agip site then googled the names mrntioned in MSDS and found Chevron Phillips Chemical MDSDS of what I think are common PAOs see for yourself. Looks like PC 5W-40 is group III after all, but the rest appear to be real synthetics not bad I can get both 5W-50 and 10W-60 for CAD $ 7.00 this should be well worth it
