dumby light ? while towing
78f150 4x4. has a 400.
-While towing my 18' ski boat today, down a 13mile stretch of 55mph highway, i got into town and started to slow down to 35, but slowly decrease in speed. when i was almost completely stopped(for the red light), my oil light came on. I quickly shifted to neutral to shut down my truck, and the light turned off.
put back in drive and it starts to blink. but stays on until i give it some skinny pedal.
so onto my ?
-why would my oil light come on all of a sudden, and why does it turn off when i put it in neutral(its an auto trans).
-would engine temp. have anything to do with this? the temp gauge was almost to the far right H side.(and any ideas why it got so hot??)

The rpms increase in neutral versus in drive. So, for example, if you have less than 5 psi in drive, the light comes on. Shift to neutral and you get 7 psi, the light goes off.
There may or may not be a problem and the best thing to do is get a mechanical oil pressure gauge so you know EXACTLY what is going on.

Well said. There's not much you can do to diagnose the problem until you can quantitatively establish the oil pressure's behavior.

well i pulled it home this morning, before it got 95degrees. didnt have a high engine temp. or oil light come on. im thinking some of my engine heat problem may be comming from the fact that i dont have a fan shroud, but at 60mph the air should be blowing right through the radiator. which now means i have to pull my boat up to *******,mi with my pathfinder...i know, im heartbroken...
