The QS UP FS data sheet for 5w30 still has a working link to download. That's the one I looked at 2 weeks ago and its specs are excellent. I also previously downloaded 0w20 & 5w20 data sheets 2 weeks ago and they are excellent too.
Tonight I notice that the links to 0w20 & 5w30 data sheets are now broken links. For some reason, there are now two 5w30 links - one broken & one working.
I think it's incompetant website management by QS or SOPUS website maintenance IT staff. I'm an IT manager myself. I recognize it as incompetance by whoever maintains the QS website. If it was intentional, they'd fix or remove the broken links, not leave them dead.
I don't assume the dead links mean the oil is being discontinued.
The incompetance of their website maintenance people has nothing to do with the people who make the oil or the products they make, IMO. Though it's not exactly a ringing endorsement of the SOPUS middle or upper management business office. They should be embarrased.
I attached page 2 of each data sheet (0w20 & 5w30) that I downloaded 2 weeks ago. I did not download the 5w20 data sheet 2 weeks ago and now its link is dead.
