Engine Oil Preesure Gage
Your oil pressure gage shows the oil
pressute .in psi (ptiunds per. s-quare
inch)
or l engine is runnhg. Oil pressure. may
vary with engine -speed, outside
temperature and .oil viscosity. In fact,
while the engine Is warmirig tip, the oil
pressure will be higher than at the
:normal operating ternpaature,

indicate the.,normal operating range.
If.the gage reads in the shaded area
when you’re idling and stays therej oil
