    Cadillac XLR

    2005 Crimson Pearl

    Default Low Oil Pressure at warm idle!

    Just curious. I have a 05 XLR with 47k miles always maintained, but at running temperature idle it is around 16-18 pounds. Is this normal for the Northstar or could I have a bad sender. On acceleration it goes right up to 50 pounds plus.

    About right. The N* has surprisingly low oil pressure at idle.

    I figured that was more than likely the case, Thanks for confirming that.

    For your (and others) info, taken from my X:

    Oil life at 65% left, normal operating temperature, correct oil fitted:

    * At idle: 18-19, maybe 20
    * At 1,000 rpm: 40
    * At 2,500 rpm and higher: 60

    Running slightly hotter than usual (heavy traffic stop/start), temp rising to 220
    * At idle: 18
    * Other rpms, same as above.

    That is pretty much where my car is. Feel much better about it now. Thanks for the info.
