Todays engines can run a lighter viscosity oil is because of the fast baud rate and power of the computers that can advance and retard each cylinders timing . But more boost increases the load on the components and the bearings a bit thicker oil or higher HTHS rating is harder to push out of the crank and rod bearings [Thicker oil wedge.]
