Hey guys, I noticed after the truck warms up my oil pressure gauge (factory) goes almost down to the first red line. Theres 2 red lines, first being 0psi and second being 10psi. Now I know the rule of thumb is 10psi for every 1k rpm. So at idle, 700 im at 12psi. and on throttle im back up to near 35psi. Was wondering if this is normal. My last truck i dont recall it doing this. When its cold it stays up to 35psi, till the truck gets over 140 then its starts slowly dropping when the truck gets warmer.
Thanks guys.
Nick
ohh and the truck has 119k miles on it.

 

mine did that to i started to put 14 quarts in and it idles at near 40 wot its almost 80

 

You can't reley on the factory gauge it's just a glorified idiot light! If you wanna really know what's going on your gonna have to get a real gauge hooked up to a sender in the block. Unlike the factory one that's hooked to the ECM and sends the gauge a "fake" what you wanna see based on temp and rpm input.

 

Interesting nick, your old one was an 06 and mine is also an 06 and doesn't have the problem you described earlier wonder if it's coincidence or what's going on, who knows dude, let us know when you find out

 

Nothing to worry about normal. As long as it moves your good they are not so precise!
