Try kmans oil. Hered linkI live in Michigan and was talking to the owner of the dealer ship and he asked about my car. I told him that I would be in to get the oil changed soon,and he informed me that they were having trouble getting the filter and the oil for the 5.0 engine . He said that if I could get it they would install it for me at no charge and record the service. I am capable of doing it my self but while it is under warranty I want the records to show them doing it . I am amazed that even maintains parts would be hard to get!
