The 5.3 engine should have oil pressure between 40 and 60 PSI when it is at idle. If the oil pressure is lower than this, it could be an indication of a problem with the engine.
If your 5.3-liter Chevrolet Silverado is idling and the oil pressure gauge reads between 20 and 40 pounds per square inch, that’s within the normal range. If the reading is below 20 PSI, there could be a problem with the oil pump or pressure relief valve.
HOW TO: TEST & FIX LOW OIL PRESSURE IN YOUR 5.3L OR OTHER LS?
5.3 Low Oil Pressure at Idle
If you notice your oil pressure gauge reading low while the car is idling, there are a few potential causes. The most common cause is simply that the oil level is low and needs to be topped off. Another possibility is that the oil isn’t flowing correctly due to a clog in the filter or line.
If you recently changed your oil, it’s also possible that you didn’t put enough in.
If topping off the oil doesn’t solve the problem, then it’s time to take a closer look. Start by checking the condition of your oil – if it’s old and dirty, it could be causing problems.
Next, check your oil filter and make sure it isn’t clogged. If everything looks good so far, then it’s time to check the oil pressure sensor itself. This is located on the engine block and can sometimes get gunked up with dirt and debris.
Cleaning or replacing it may solve your problem.
If you’re still having trouble after all of this, then there could be an issue with your engine itself. Consult a mechanic for further diagnosis and repairs.

Is 20 Psi Oil Pressure at Idle Ok?
If your car’s engine oil pressure is reading 20 PSI at idle, then that is considered to be within the normal range. Your car’s oil pump is responsible for circulating the oil throughout the engine and maintaining proper oil pressure. If your car’s oil pressure is reading below 20 PSI at idle, then that could be an indication that there is an issue with the oil pump or a possible blockage in the oil passages.
If you notice any decrease in your car’sengine performance or fuel efficiency, then it would be best to have it checked out by a mechanic as soon as possible.
What Should My Oil Pressure Be When Idling?
If your car has an oil pressure gauge, it should read between 20 and 40 pounds per square inch (psi) when you’re idling. If your car doesn’t have a gauge, you can check the oil level with the dipstick. The oil should be at the full mark on the dipstick.
How Much Oil Pressure Should a 2011 5.3 Have?
If your 2011 GMC Sierra with the 5.3-liter V8 engine is idling, you should see between 40 and 60 PSI on the pressure gauge. If you’re driving down the highway at a steady speed, it should be around 20 to 30 PSI.
Is 40 Psi Oil Pressure Good?
Oil pressure is one of the most important things to keep an eye on in your car. It’s a good idea to check it regularly, and if you see any changes, take your car to a mechanic to have it checked out.
40 PSI is considered the standard oil pressure for most cars.
However, there are some cars that require higher or lower oil pressure, so it’s important to check your owner’s manual to see what is recommended for your car. If you’re ever unsure, it’s always better to err on the side of caution and take your car in for a check-up.
Conclusion
The oil pressure in a 5.3 engine should be at least 40 psi at idle. If it is lower than that, there could be a problem with the engine.
