0W20 or even 0W30 won't cause engine damage. The only engines that don't like different viscosity are the HEMI MDS and GM's DOD engines. They're particular about running nothing but 5W20. You could run 15W40 even in a VVT-i engine for all the dealer knows. They won't spend the money to test oil viscosity if a warranty repair comes up. 0W20 will allow for smoother starting in cold climates as the oil will move faster to all vital components. As long as the oil you want to use is labeled on the bottle that it is compatible with a particular manufacturer then there's nothing to worry about. I run Amsoil in all my vehicles with different viscosity. Amsoil even backs up their product with their own warranty should anything happen to the engine and it was proven that the oil was at fault - Amsoil will cover the expense. I've been an Amsoil dealer for four years and have sold thousands of quarts to people with everything from a '08 Audi A8 to a '89 VW Rabbit diesel.
