Today I got a call from my dealer to pick up my ecoboost mustang from some warranty work I was having done. When I got home I looked at the invoice (I know I should've looked at it before I left) and saw that they filled it up with 5w20 when the manual says to use 5w30. Should I change the oil right away?
