Question

A proper oil pressure range with the engine "operating" is ________.

a) 10-20 psi
b) 20-40 psi
c) 40-60 psi
d) 60-80 psi

Answer 1

The proper operating oil pressure range for many car engines is typically between 20 to 40 psi, but it's essential to consult the vehicle's user manual for exact specifications.

Step-by-step explanation:

The proper oil pressure range with the engine "operating" depends on the type of engine and the manufacturer's specifications. However, a common range for many engines, particularly for car engines while they are running at normal operating temperature, is between 20 to 40 psi (pounds per square inch). Low oil pressure might indicate a leak or that the oil is too thin, while high oil pressure may suggest a blockage or that the oil is too thick. It's critical to check your vehicle's user manual or a reliable service manual for the exact oil pressure range for your specific engine.

Answer 2

The proper oil pressure range with an engine operating is typically 20-40 psi, which ensures adequate lubrication and cooling for engine components.

Step-by-step explanation:

A proper oil pressure range with the engine "operating" is typically 20-40 psi (b). This range is sufficient for most car engines under normal conditions. Lower pressure can indicate a serious problem such as a leak or a failing oil pump, while a pressure that is too high might suggest a blockage or an issue with the relief valve. It is important for oil pressure to be within the specified range to ensure proper lubrication and cooling of the engine components. Oil pressure below this range can lead to insufficient lubrication and potential engine problems, while oil pressure above this range can indicate a restriction in the oil flow or a faulty oil pressure relief valve.
