Most 5W-30's shear down to a 20 weight after a long oil change interval. But 5W-20's usually stay pretty much where they start. The car is breaking in, so that's why the Viscosity is where it's at.
i see the Amsoil OE and XL (I currently have XL in mine) start at 8.3, but the Signature series starts at 8.7. and is what I have been planning to run starting next fill.
