lotsa miles & the Scientifically Treated Petroleum has lotsa zinc. b4 the 62 I only used stp for engine building & the occasional oil hogs. BTW the late 80's 5.0 used low tension rings that were kinda oil hogs from new. ford would re-ring them for you if they consumed more than a quart in 500 miles. they ran good & they ran forever & by the time you had a 100k on them they usually quit using oil. I had a 90 5.0 lx bought new & it never used oil so they must have been redesigned by then, but 88s & 89s were notorious oil users.
