ENGINE OIL PRESSURE GAGE
CAUTION
At 1,700-2,100 rpm, the minimum engine oil
pressure for safe operation is 30 psi. If, in
this rpm range, the gage does not show at
l e a s t 3 0 p s i , s t o p t h e e n g i n e i m m e d i a t e l y
and investigate the cause.
Registers engine oil pressure in pounds per square
inch (psi) and kilopascals (kPa). Idle minimum is
10 psi. At rated engine speed (2,100 rpm), normal
range is 35-50 psi.
