Question, I have a 2013 4x4 Silverado Crew cab. I think my oil pressure is running to low. It gave me a code it was to low. I've had the oil sending unit and screen filter replaced and code clear. When I drove it to work tonight it's low again. When I started it 40 + lbs, if I push on the gas very much it moves up and down some with speed. But while I'm driving it normally it drops to around 20. Then when I parked in parking lot at work and let it idle it goes down to about 10. This truck has the drop out cylinders on it to make it a 4cyclinder. What do you think. Can it be the oil pump or something else.

My 09 Silverado LT, 5.3 Vortec, not the flex fuel edition. 32-35 psi at 400-600 rpm idle (cammed). 36- 38 psi at 2000 rpm cruising speed (77mph). 40-45 when running her hard (3500+ rpm).

All depends on oil as well. In northern states, where it’s colder, you would use a higher viscosity oil (thicker), so oil pressure would be higher. Warm states like the one i live in would use regular or even lower viscosity oil. Even running full synthetic or regular motor oil can affect oil pressure. It’s many factors, so every truck is different, but most answers should be at least somewhat close together.

My 05 runs at about 32 to 34psi with 360,842 miles on it. Have never had to any motor work to it even pulling a 32' fatherlight camper all over the US. But finally starting to get metal shavings in oil. What is the best route to go to rebuild and get me about another 100 horses or so?
