    If your pressure is ok now- maybe it was just a wonky gauge? I would give the 15w50 a try anyway .

    I switched from the 5w30 to 10w30high mile oil.It didn't hurt my mpg and my warm idle pressure is maybe 22 psi instead of 20 psi.

    my 1998 has 210,000 runs great.
    Thanks, Charlie!
    I will definitely change over to 15W50 at the next oil change. I know Chevies run with lower oil pressure, but my Mercedes diesel with 311000 miles on it runs at over 50psi even hot.

    My truck usually runs under 200 degrees unless I am going uphill with the AC on, then she might go up to 210.

    I am thinking it is a wonky gauge that is why I want to plumb in a mechanical one at least to confirm the readings. I just don't know where to put it on a OBDII Vortech engine. I usually just pull out the sender and replace it with the gauge connection on my older cars with idiot lights... I don't want to upset the ECU by taking out a needed input
    I have no convictions ... I blow with the wind, and the prevailing wind happens to be from Vichy

    I will swap that this weekend. I have seen the temps fluctuate from under 200 to 210, but never higher.
    Again, it could be the gauge cluster. I really need to replace it,but for $300+ I have been living with it.
