I probably don't want the answer to this, but I'll ask anyway. My car was running fine the other day, today I go and start it, and the oil pressure drops to almost nothing. Light goes off etc. I drive around the block, and as i step on it, the gauge goes up, but even if kept at the same rpm, it drops while i watch it, back down to 'the red area'. I've read of oil pressure sensors failing, but I'm guessing in my case its probably the bearings, or the pump itself. I check the oil level, its fine, and there are no visable leaks. Also the oil isn't milky or discolored in any way. I am do for an oil change but I don't think its normal for oil pressure to be like this even if a change is due. Any help is appreciated.

Could be the needed oil change. Depends on how far over 3,000 miles you are. If there'* no knocking and no other problems. Do the oil change and hope for the best.

Usually when a pressure sender fails it defaults high or erratic.

Oil can get thin as it gets old. It shouldn't be an overnight thing, tho.

I would definitely start with a good oil/filter change (about 20 bucks) before diving into or assuming more expensive ideas.....

i would not drive the car, and to be sure what your OP actually is get a mechanical gague on there to verify

Most likely the gauge is reasonably correct. An oil and filter change is in order before driving the car. Hopefully that'* the issue. If the bearing are going or gone, oil pressure will not return and it'* only a matter of time before the knocking sound starts.

Thanks for the help guys, I started it again, pressure starts at around 35, the drops sharply after a minute or two, one drop to like 30.. then again... then it inches down... after like 5 minutes or so, its in the red. I will try changing the oil, hopefully that'll give me enough pressure to get it where i can have it fixed.

It is full, right? I would assume you checked the oil level, especially once the engine is warm.

And what color is the oil? Nice chocolatey brown? Or tar pit (aka Change it already!! ) black??

Had this same problem. Changed the Oil pressure sensor and alls well. May want to check your connector to the sensor as they get very dirty sometimes??
