Oil Light on

[Sheldo]

So I have a 98 Catera and recently my oil light came on. I didn't think much of it and did an oil and filter change. When further examining my problem I notice that I've been getting 15-20psi lower than I use to and my oil light is still on. Any suggestions on what's going on and what I can do to solve this problem?

we have come across this over the years seems to be a trend with catera but usually not an engine damaging situation, to be honest we have found that replacing the oil pressure sender and doing an aftermarket oil flush on the engine does cure tyhis in alot of cases, i dont recommend anything aftermarket due to the fact i work in a caddy dealer but ...... it does work for me sometimes. my flush system that i use only for problem vehicles is valvoline and it does work.

I just replaced my engine 5000 miles ago and when I got the engine it was dry to begin with. I've done 2 oil changes already, one at 2000 and just another one last week at 3000. So would you still recommend another flush? I don't feel like going through again and flushing out my oil when I could have done it last week, I'm only 19 and in college, the money isn't around much lol. So where is this sender located and how much am I looking to spend on it?

So I've been driving around for 100 miles after the oil change. The pressure went up to what I'm use to regularly seeing but the light is still on.
