To keep the door latches operating properly, the car shop manual for my
1991 Mercury Grand Marquis states: "Using lubricant D7AZ-19584-AA or
equivalent, spray into latch opening and manually cycle ten times."
Does anyone know what type of lubricant this is and where it might be
purchased other than a dealership?

Won't help the door latches at all doing it that way. That only helps
the lock cyls. ANd I THINK the referenced lube is heavier than the
colloidal graphite you refer to. It is noted as "multi-purpose grease"
Neo 1:11 is a penetrating or creeping spray multipurpose grease.
Chevron FM EP is food grade, but will also work.
KC SlipShot is a red penetrating grease, and some of the clear lithium
greases are good too. I am not a fan of "lubriplate".
Wurth HHS 2000 is possibly the most widely available (proffessional
product) and is excellent - as are MOST of Wurth's products. Pricy,
but usually worth it.
I have used Castrol Motorcycle chain lub - very effective, but dirty
For noisy door check-straps (a big problem on a lot of Mopars - and
some Fords and others) I use anti-seize. Anything else generally lasts
just long enough to get it out the door.
