Normally I think the oils "Vollsyntetische" under german law are better for carrying a higher percentage of PAO and being Group IV.
I use Motul Specific dexos2 5W30 because it is "Vollsyntetische" but I was interested in the Shell Helix Ultra AG 5W-30 Professional
http://www.shell.de/products-services/on...ro-ag-5w30.html "Motorenöl auf Basis von Synthesetechnologie" that is not 100% synthetic under German law.
I get susprised because is comparing both I think, by numbers, the better is the Shell. There are not very distinguishing figures in their technical reports but it has caught my attention because I expected better results in the french oil than the dutch one.
Is there any expert who can tell me which is better? Or maybe one is it better in terms of protection and the other in terms of longevity or cleansing?
