What should oil pressure be at start from cold?
What should oil pressure be at start from cold?
Our old 850 engines have a relief valve that is supposed, by design, to open at 45 psi, according to published data. On my engine the gauge pressure shows 55-65 psi at start from cold, then settles down to about 45-55 psi at cruise speed, with about 20 psi at idle.
What should the oil pressure be in a car?
If your oil pressure light is flashing on your dashboard, you should stop your vehicle and turn it off imminently! So…What’s the Ideal Oil Pressure? The ideal oil pressure ranges between 25 to 65 psi when the engine oil is warm and 1000-3000 rpm, whereas if the oil pressure reading shows 80 psi or above then there is a serious problem.
What should the oil pressure be at idle?
On my engine the gauge pressure shows 55-65 psi at start from cold, then settles down to about 45-55 psi at cruise speed, with about 20 psi at idle. I consider this the normal thing. One of the other participants in the discussion boasts that his engine is better because it shows 120 psi.
When to know if your oil pressure is high or low?
Before concluding that your car has a high oil pressure problem, it is a good idea to first check that the oil pressure gauge is working properly. If the car is on idle and the engine oil is hot – you normally have low pressure. If the engine oil is cold and you rev up your engine, the gauge should be much higher.

What causes low oil pressure in an engine?
Oil pumps have a reliefe valve to prevent excess pressure when the oil is cold and thick and maximum pressure is limited to well below 100 psi in every engine that I have ever manually tested. Low oil pressure results from a worn pump, a relief valve stuck open or worn components that bleed off pressure.

What should the oil pressure be in my car?
The unit of measurement is either PSI or Bar. The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI.
