I guy I work with, inherited an early 90's Dakota with a v-6.
We are all well aware that the owner was not real good about regular servicing of this vehicle--(reads NEVER)

Tim has had this vehicle for well over a year, and has used it for trips to Dallas on a regular basis. (move kids in and out of Dorms etc.)

Every now and then the oil pressure gage drops & the light comes on.
The engine does not seem to be making any more noise than usual.
Shut the car off--restart--everything is fine.
The sending unit has been replaced, but the issue continues.
This is pretty intermittant and no real way to test without installing an aftermarket mechanical gage--(I suggested this to him today).

Is it possible that there is a problem with the gage itself---resistor or something failing, and giving a false reading.

Perhaps the pump is wigging out--Not sure if this is a reasonable thought, as I don't really see a pump "turning itself on and off" if you will.

Anyone else have a similar issue in the past--solution???

Gonna have him look into this site in the morning.

Have ran into a few engines with something other than regulator oil changes get so clogged up that the oil can't get back to the oil pan quick enough before it drops oil pressure, cut the engine off oil returns light go off on restart , have got lucky on some by adding a quart of transmission fluid to oil and changing oil every week with trany fluid added every change for four or five weeks get the engine clean enough to survive. Just a thought.

On his way home from work yesterday, the 'lil truck made it all the way to his exit on the freeway (40+ mi commute each way).
As he eased off the accellerator to the offramp---pressure started to drop.
He thinks to himself--"Accellerate and the pressure will go back up."
Pretty logical thinking, if you ask me.
No such thing happened, pressure drooped to "oops" and the light came on again.

He looked at this thread today--might try the ATF trick. He is also planning to pull the pan for an inspection. Maybe there is a paper plate or something getting sucked up to the pick-up.

I don't think he is in a hurry for a solution, as he does not drive the truck on a regular basis (although he might if were working correctly )

I've always seemed to have better luck using Marvel Mystery Oil and doing this same procedure. ATF should work though.
