    Default Low oil pressure in 2000 tundra?

    Yesturday i notice my oil pressure seem a bit low was in between 1/4 and 1/2 mark at idle and once it would warm up it would sit just above 1/2 mark and when i stop at a stop light it goes down to 1/4 mark but when i'm driving at about 2k rpm its almost to the 3/4 mark, is that normal i though it should be around the 3/4 mark at idle. i'm running amsoil 0-30w.

    If you're running 0w30 I would expect the cold pressure to be less than someone running 5w30 or 10w30. For me, on cold startup at idle the pressure is at about 1/2, at 3k rpm it gets closer to the 3/4 mark. Once it's warmed up it'll sit just above the 1/4 at idle, and just above the 1/2 at 2200 rpm (highway speed). I'm running 5w30 amsoil synthetic.

    This has been covered ad nauseum. It's TYPICAL, EXPECTED, and NORMAL functioning for a crank-driven oil pump.

    To add to Remmy's observation what you are seeing is a normal and perfectly perfect readout from the oil pressure.

    What if it goes lower than the 1/4 mark after warmed up and at idle . How low should you start to get concerned?

    If it normally reads at or above the 1/4 mark at warm idle & then suddenly reads lower you need to worry as to why. If it always reads that way then possibly this link will explain and provide a solution.
