Olas, the 2.0 Ecoboost engine requires 5W30 oil.
Climate dicates viscosity - 5w30 is appropriate in some places but not others.
Point remains - for gentle use in trafiic with the kids as passengers, xW20 will be just fine but for sustained high temp/high load you need lots of capaity to deal with heat, and lots of AW.
