To be honest (And nothing against the 2nd gen Escorts...far better car than the 3rd gens, ITBJHO)
Put whatever's cheap in it man
That 1.9 will go 300,000 miles with "whatever cheap crap my mechanic puts in it" (Grampa's words, not ThunderbirdJunkie's)
The Grampa has owned no less than - no exaggeration - TWELVE Escorts and Tracers, about 50% bought new, since 1983, and all of them have had AT LEAST 200k on them before they got sent to the scrapyard.
If ya need to know anything about a maintenance regimen that will make the car last forever, ThunderbirdJunkie will ask his grampa. He has it down to a science...he's got an 86 wagon with 220k on it (bought new, granny drives) and an '02 (which he only bought because it was the last year for it and the good ol' motor he's "YOUSTA WORKIN ON") with about 75.
that '86 is a better driving car than one of ThunderbirdJunkie's associate's 99 Escort ZX2 5 speed with a bunch of new parts and 80k on it
