When was your oil last changed? That inline 6 cylinder could have some sludge buildup in it. 50-60 is normal, my dads 03 sierra is at 60 and so is my step moms 01 blazer.

Oil change time.

I'm having same issue. Did you ever figure out the issue? I just had my oil changed and it still does it.

Heavier oil which oil thickens the colder it is, bad sensor or wire to the sensor, sludge build-up
