Need help with this because I made horrible error of taking wife with me to get oil change at Valvoline. They say that my 2011 Hyundai Elantra Touring requires semi-synthetic oil, which costs 50 dollars for an oil change out the door. She said no way. So I got oil of proper weight but not proper quality according to Valvoline.
Help? Who is right, Valvoline or wife?
