Oil pressure when cold.

It is really get getting cold down here around 12F this morning.
It snowed about 6 inches and the wife wanted to use my jeep so I fired the old power wagon up to take it to work.
The old gal cranked right up first try, but I looked at the oil pressure gauge (factory electric).
It read a little bit over 0 psi. Let it warm up until it was melting the snow on the windshield.
It read about 5 psi. :wack:
On a warm day the old truck starts and goes to 40 and idles hot at 20.
The old gal has 10w-40 in it but it is way to heavy for the temps we are seeing.

Tonight it is supposed to be around 1F, I put a magnetic heater on the oil pan to help it out in the morning.

There was no ticking in the top end, just want you guys to know to let you old cars/trucks warm up before you run them.
