Re: 1986 P'up - intermittent oil light

Simple old age With that milage the bearings will have worn as well as the pump so the pump has to work harder to supply more oil but it is no longer as efficient as it used to be.It is the start of the end of the engine but it could easily go anouther 20000 or more miles before finaly expireing. You co uld try oil one grade thicker if it worries you
