Bought a 87 F150 5.0 that had 105k miles from a guy that had it since new. I kept the same oil change regimen he did. (Mobil Del-vac 15w40 and a bottle of STP) Don't ask me why I just done it. With a name brand filter, Motorcraft mostly. When rust finally ate up the truck to where you could not drive it anymore the engine had 367k miles and still going strong.
