Engine/Transmission (1998.5 - 2002) Oil Pressure when COLD ?

[chazj]

Here is the scenerio. Started the truck this AM without the aid of the block heater (forgot to plug it in). Outside temp was just above zero degrees.

Dealer put in 15-40 synthetic last oil change in October. While "on the road" I've had to start the truck in below zero temps without any "issues" or problems.



The Oil Pressure Guage has always started to immediately rise, abeit slowly, under these cold conditions. Today however it appeared to "just sit there" and then Suddenly it rose to it's normal position... Very Quickly!



No strange sounds from the engine during this starting procedure.

Enerything appears normal from this point on.



Just curious as to WHY the oil pressure guage would act this way when it's operation has been so consistent in the past... even under colder conditions...

don't know if it's normal, but that's exactly how mine operates too. Nothing for a few seconds, then boom, it's up to normal.

our trucks are noted for oil pressure sensors going bad..... may want to look at a new one if it keeps up.

Check the oil filter and see if it's leaking around the top. It may be loose. Also a small delay in oil pressure reading is normal(couple of seconds) according to the owners manual.

Because of this delay from sendor to gauge i get to listen to my Edge juice alert me every time i start my truck. (it senses low presure and cherps at me)

On some trucks when the sensor goes out, it defaults to 40 psi whenever there is pressure. Instead of an idiot light you get an idiot guage.

Synthetic or not your oil is pretty thick when cold. Switch to 0-40 full syn & the problem is gone.

PS I run it year round
