The gauge only goes up to 70 psi and it's normal for the V6 to bury the gauge when it's cold only, once it warms up it will still hit 50 psi a lot and idle around 30 psi which is normal for the 3.6 it has a high pressure/ high volume pump for it's 5 miles of timing chains needs tons of oil dumped on them. The V8 will not bury the gauge ever.I have been seeing some weird oil pressure gauge fluctuations lately. Recently I changed the oil pressure sensor at the back of the block by the camshaft sensor.
