you want them to make it easy for them to work on?

Right? That would be too much to ask for

What is your year,make and engine size? Mileage? You can use the old sender to match up a adapter.

It’s a 1999 GMC Yukon SLT with 5.7 Vortec with 247K

So old school R code 5.7 . With 250000 best case hopefully just a gage issue,but I am sure you know 250 and 21years old. First is test. There could be a number of things going on. I would pull a little oil out and look at it in the sunlight for metal flakes. If on flakes hopefully maybe a oilpump will help. Otherwise time to pull and tear down.

It sounds like valid readings. Likely the engine bearings and oil pump are worn. The positive side is engines don't require much oil pressure at idle. A 20w-50 oil may help.

Having an accurate pressure reading will help alot. put a gauge on it. i have seen them idle at 5-10 PSI and live for a long, long time. 10w-30 or 20w-50 may help. 10W-30 works ok in cold climates too. You really need to know what the pressure is at idle.

Okay! The hard part is working on it, cause my apartment complex you can’t work on your vehicles! (Plus I work where I live, so I HAVE to set a good example.. lame) I’ll get a gauge and give it a test! Would an oil flush help maybe?? I’m trying my hardest NOT to tear anything up, considering I’m a 22 year old with very little to none mechanical experience..

I wouldn’t flush it. With that many miles you are asking for trouble.

Did this start before or after your oil change?

Before, figured it was as simple as replacing the sensor!

Honestly, give us a pic of your COLD dipstick.

I know it's dumb, but sounds like low oil.
