Great oil pressure at start up.
When I start in the morning I have great oil pressure, but after my 91 4runner w/3.0 warms up it seems to have low oil pressure? I use Quaker state 5w30.
Any thoughts or is this just normal

As the oil heats up, it also thins out and thus the oil pump will make the most pressure when the oil is thicker (ie when cold). If you put in 10w30 I bet you will see the pressure go up slightly when warm.
