NOTE ❵● Position of instruments shown is normal but some trucks may have instruments in different positions. ● Normal oil pressure with engine running at idle speed is about 10 psi (69 kPa). With engine running at road speeds, en- gine oil pressure should read about 45 to 60 psi (309.275 to 413.700 kPa). ● Some engines have normal oil pressure readings between 40 and 75 psi (275.800 and 517.125 kPa) at road speeds. If your oil pressure gage has a maximum reading of 60 psi (413.700 kPa) and the needle peaks at 60 psi (413.700 kPa), notify or- ganizational maintenance. They will re- place the gage and sending unit with one that can measure a higher range of oil pressure. Change 2 1-11
