Would the restore and protect Valvoline be better for the K4 over the European?

It would be better regarding the Euro spec oil higher HTHS and TBN too, and total oil longevity.

Might want to check the lower left radiator hose for a possible kink . It could possibly impact the flow . Seen it in the video below at 2:40 while looking at oil change for the K4 . Is a good looking vehicle . Enjoy
