Each vehicle will have a slightly different proper oil pressure, and it also depends on the season of the year. Generally speaking, a good pressure is 10 at idle, and 45 at 3,000 RPM.
Oil may be thinning out when vehicle overheats and cannot maintain proper oil pressure
40 to 60 lbs
it needs a tune up
Low of the proper amount of oil. Oil pump is defective. Oil pressure sending unit it defective. Gauge, if equipped, is defective.
The oil sending unit is bad or the oil pump is not pushing enough pressure.
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.
either oil pump is bad or oil gauge sending unit is bad.a lot of engines have cut offs when oil is not showing proper pressure
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.
Normal is 20 to 60 psi.
Oil pressure lights indicate improper oil pressure. A pressure sensor is mounted on the engine to monitor the pressure. When the engine oil pressure drops to a level below the perameters required for proper engine operation as determined by the manufacturer, the sensor acts as a switch to complete an electrical current, illuminating the light. Low oil pressure can be caused by, among other things, insufficient oil level, or internal engine component wear, including a worn oil pump.
If it is for real, and not a faulty sender, low oil pressure will result in insufficient oil supply to moving parts and surfaces causing excess engine wear and possible engine seizure. If you do not have a proper oil pressure gauge, get one, senders are as useful as an udder on a bull.
In a car no as long as oil pressure maintains proper level In a motorcyle remember this is also transmission lubricant and proper oil should be used pwer manufacturers spec.
