low oil pressure
 

My 95 runner on start up reads right in the middle on in dash guage, but once warm and at an idle it's burried at low? (engine 3.0) Should i change the pressure sensor? or is this just normal???

What weight oil are you running?

10w40 with a bit of lucas oil stabelizer... This is my first toyota and i wanna take good care of it.

I find 10W40 is about as light an oil as I can run in my '85 in the summer to keep the idle oil pressure up. I usually run 15W40 and that seems to work fine. Might also try hooking up a mechanical pressure gauge to verify the real pressure, maybe the factory gauge or sender is not reading right.
