Oil Pressure Gage

United States
The engine oil pressure gage, on the lower right
portion of your instrument panel cluster, shows
engine oil pressure in psi (pounds per square inch)
or in kPa (kilopascals). Oil pressure may vary
with outside temperature and oil viscosity,
but readings of 30 to 40 psi (205 to 275 kPa)
are normal. The normal operating range should
be between 35 and 70 psi (240 to 480 kPa).
