I don't remember reading this in the owners manual for my '92 package B, and
i don't yet have the shop manual.....what are the desired oil pressures when
idling & at various RPM?  The reason i ask is that i recently changed the
oil myself for the first time, and while i put in the amount of oil the 
owner's manual says (3.8 quarts? something like that) the pressure seems
to be higher than i remember it being before.  

The oil pressure at start up idle is about 70-75, and if i drive before 
letting it warm up at least 10 minutes, the needle sometimes come close to
hitting the 90 mark at about 2500-4000 RPM .  After about 20 minutes of 
driving or so, the pressure stays between 25 & 65 or thereabouts

are these typical readings?
