A Honda S2000 could do magic: I could make a 5w-40 out of Mobil 1 5w-50 in no time. About Two trips to the grocery store and this oil is sheared down. This was proven in the german Honda S2000 Form. There is one guy wich claims to work at Mobil Germany as Engineer / Chemitrist wich reccomends this oil because, he explains, after it sheared down it is "Stable" over the OCI.
So, sorry when i am VERY, VERY sceptical about a oil wich contains a lot of VI Improvers in a really high reving, demanding engine.
