When I switched to full synthetic from dino my oil temperature dropped. I
do not remember a change in the pressure. The temperature is still consistent
with the original observation. My pressure gauge is not currently wired. I
am running the oil pressure off a VDO dual sender. I am running the temperature
off a VDO temp sender located near the same point.

Was running a 1.6L highly modified system in a 1979. Now running a highly
modified 1984 1.8L in my 1979.
