normal oil pressure is 48 to 60
The oil gets thinner. It is normal for the oil pressure to drop after the engine has reached full operating temperature. If you have from 30-40 psi pressure when the engine is hot then that is normal.
The normal oil pressure on a GM 305 engine is between 40 and 60 PSI depending on the model year. High oil pressure is needed to allow for proper circulation through the engine.
It will vary, depending on engine load, but at idle it should be around 30-35PSI. On a light to moderate throttle, it will dip slightly to 25-30 PSI.
Need to know the year.
Oil pressure has to built up. As long as the pressure is normal and the oil level is good. There is no problem.
It is normal for the oil pressure to drop when the engine is warmed up and at an idle.
A good rule of thumb is to look for 10 pounds of oil pressure (or more) per 1000 RPM of engine speed. Below that, the engine may not get proper lubrication.
No. The atmospheric pressure is too low. Perhaps an internal combustion engine could be designed to operate on Mars, but it would not be 'normal.'
Oil pressure gauges are notoriously inacurate. Pressure should be high when the engine is cold, or the accelerator is pressed hard. It's also possible the sensor is damaged.
what is normal blood pressure
Engine hot - normal Engine cool excessive pressure bad thermostat
Engine crankshafts usually break when there is too much pressure on them. Some have flaws and may break under normal use.
The normal oil pressure on a 2002 Chevy S10 V6 is around 40 PSI. This will vary slightly depending on the temperature of the engine. Hot at idle in drive, 20 psi is also normal.
about 20psi at idle (warm) and 40 to 50psi at 2000rpm.
Running at operating temperature around 40 psi.
56 psi at 3000 RPM engine warm
replace the oil pump or the engine could blow
It should be 30-35 psi with the engine running.
40 - 80 psi at idle, depending on what the engine is.
My 1992 PA with a 3.8 engine has a a 195 degree thermostat. This causes the normal engine temperature to be about 205 degrees. The pressure cap will keep the fluid from boiling up to about 240 degrees.
When the engine is cold it will have a higher oil pressure than when it is at full operating temperature. The normal pressure also varies from one make & model vehicle to another. A Ford may not have the same pressure as a Toyota. 40 psi is about normal for most engines.
As the engine speed increase so does the speed of the oil pump. the faster the pump turns the higher the pressure becomes. When changing gear the engine speed drops along with the oil pressure.
