5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
On the 5.0 that I just sold I used valvoline maxlife since it was more of a daily driver and was somewhat stock. besides, it had 147,000 miles. I really liked this oil because my car stopped burning oil and stopped leaking it. I also saw the oil pressure go up a bit. (10w40)
