Interesting Vid...
I'm a fan of Amsoil Signature synthetic engine oil (5W20)... All synthetics seen to lubricate and flow well. All are pretty good. My choice was base on the three areas where Amsoil simply eclipse the others in testing: (1) extremely low NOACK volatility rating, which is very important in GDI with turbo, (2) the off the scale resistance to high temp shear, and (3) the Amsoil synthetic also has the lowest cold cranking viscosity despite best high temp lubrication, so it circulates well very early. Yep I do pay more...my car is worth it to me and I change oil and filter every 4-5K miles despite Amsoil's claim that it can go as much as 20K.
