Is 25 psi too low oil pressure?
Running pressure at 25 psi is too low. Idle pressure at 20 psi is too high. Your oil pressure gauge is probably inaccurate. Look for maximum hot oil pressure of 40 -50 psi and minimum hot oil pressure of 10 -15 psi with standard bearing clearances.
What is the minimum oil pressure at idle?
Cold weather can also make the oil pressure read low until the oil pump has had a chance to deliver the oil to the engine. Oil pressure gauge reading too high, or over 80 PSI while driving, especially at higher RPMs. The minimum oil pressure at idle is only 5 psi (34.5 kpa).
What was the oil pressure in my old Silverado?
In my old 350 psi would sit at 25 psi at idle and 40-50 at speed. When it was hot outside this would decrease. Due to less than stellar block machining after less than 10000 miles I needed 20/50 as my psi would drop to ~10 psi at idle. That was super scary and frustrating.
What should the oil pressure be in a truck?
When truck is first started, oil pressure is normal, around 40 psi. When engine temp starts up, oil pressure slowly falls until “Stop Engine – Low Oil Pressure” warning comes on. Switch truck off a few second, maybe 20-30, restart truck and back to 40.
What is normal oil pressure for a 2011 Silverado 5.3?

Can a low oil pressure cause engine to seize up?
Low oil pressure will cause the engine to seize up. When the oil pressure light on, it should be assumed that the engine locking up is imminent. We advise not running the engine until the issue can be properly diagnosed. There are many things that can cause low oil pressure. Below, we’ll review the most common causes:
What causes low oil pressure?
One of the possible low oil pressure causes is worn-out bearings. If you have driven the car for quite a long time, low oil pressure could occur due to worn out rod bearings and main bearings. The bearings also play an important role to keep up the right pressure of the oil.
Is the oil pressure too low?
The low oil pressure light is a warning that there’s not enough oil pressure or that the oil level is too low. This prevents the oil from going through the narrow passages to provide sufficient lubrication. Lack of lubrication can cause the engine to seize up or cause damage beyond repair.
Can a low idle cause the oil pressure light?
If the oil light flickers on and off while the vehicle is stopped or at an idle, there may be a problem with the oil sensor or the pressure is too low . At the very least, the engine should have 5 PSI when not moving. If the PSI is less than 5, this will trigger the oil light and cause it to flicker off and on.
What does the oil pressure low?
Typically, the red engine light will come on when the engine is low on oil or the engine has very low oil pressure. If this light comes on, stop as soon as possible. Driving without oil or oil pressure will cause major damage to the engine. The yellow check engine light can come on for dozens of reasons.
