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.
it should be broke in before your first oil change. I changed mine at 2500 miles when breaking in but if youve got alot of money in it i would chang it every 400 miles or so thats what some people do but it will be fine if you leave it in for 2500
In my opinion, the oil should be changed after the first 500 miles after building/rebuilding. Then change it 1k miles after that. After that, you can go the normal 3k mile interval.
