Default Oil Pressure Light on

My low oil pressure light came on today while I was slowing down.


I checked the oil, and it was low bit certainly within range. I decided to drive to O'Riellys to get some oil. I noticed during the drive that after I reached say 1,500rpm the light would turn off, ans only turn back on as I stopped. But once idling it would stay on unless I reverse it.

After I added 1 quart of oil, I drove. Same thing. Added a 2nd quart. Samething. Checked oil level. Right below full now. I did notice as well that it takes a second longer for the light to kick on now.

I'm letting it sit to see if the oil just need to get through the top down into the pan.


Thoughts?

Thoughts? How the heck did you let it get over two quarts low? It only holds 5 with a filter! What do you consider "within range" ?

You'll be lucky if only changing the oil sending unit with solve your light problem. Many owners have had to change it.

I agree 100%. 2 quarts low is certainly NOT within range.

It's most likely the sending unit, but there is still a possibility that the oil pump is weak and your oil pressure actually drops off at idle speeds.

Look into this immediately. If it's the sending unit, you're in no danger, but if the presssure is actually dropping off, you want to fix it before it costs you an engine.

My mistake, I got it out of order. I checked the oil, AFTER I added the first quart. So then it was in range.


I have driven it a little since adding oil and it hasn't done it since. I'm still going to drive the GF's Mustang for a few days so I can trouble shoot it.
