I used Mobil 1 for 125K miles on my last Z, it's still on the street running great and I never had to make any serious repairs except normal maintance. That alone should tell you that Mobil 1 is damn good synthetic oil! Screw the tests this is real life experience....Plus, when my rear main seal failed they pulled my oil pan it was as new inside with no residue/gunk at 117K miles. This is only possible with quality synthetic oil....

but from the tests, it's clear syntec just performs better, under the exact same driving conditions and the same exact engine, the wear levels were lower and there were higher levels of anti-wear additives.
considering m1 and syntec cost the same, i think syntec is the way to go
