* Idle: 15-20 PSI
* Medium: 35-45 PSI
* High: 55-65 PSI
Factors Affecting Oil Pressure
* Engine Temperature: Oil pressure is higher when the engine is cold and decreases as the engine warms up.
* Engine RPM: Oil pressure increases with engine speed.
* Oil Viscosity: Thicker oil will result in higher oil pressure than thinner oil.
* Oil Filter: A dirty or clogged oil filter will restrict oil flow and decrease oil pressure.
* Oil Pump: A worn or damaged oil pump will not be able to generate sufficient oil pressure.
Low Oil Pressure
Low oil pressure can be caused by a number of factors, including:
* Low oil level
* Dirty or clogged oil filter
* Worn or damaged oil pump
* Leaking oil seals or gaskets
* Excessive engine wear
High Oil Pressure
High oil pressure can be caused by a number of factors, including:
* Overfilled oil pan
* Thick oil
* Restricted oil flow
* Faulty oil pressure sending unit
It is important to maintain the correct oil pressure for your Cummins diesel engine. If you are experiencing low or high oil pressure, it is important to have your engine inspected by a qualified mechanic.
